by the principle of flory-schulz principle and if the average probability of reactive functional group is 0.985, please calculate
This outcome is compatible with the lambda-parameterized Poisson distribution's Mw formula.
The use of "average"?To compare different quantities of the same category, averages are utilised. For instance, because there are disparities in the salaries of multiple employees, averages must be used to calculate the per-employee salary of a firm.
(a) The Poisson distribution can be used to determine the probability function P(x) as a function of the degree of polymerization x:
P(x) = (lambda^x / x!) * exp(-lambda)
where lambda = -ln(1 - 0.985) = 4.199 is the average number of reactive functional groups per polymer chain. The probability of finding a chain with DP = x is proportional to P(x). The plot of P(x) as a function of x is shown below:
P(x) plot
(b) The weighing function w(x) for calculating Mw can be calculated as follows:
w(x) = x * P(x) / sum{k * P(k), k=0 to infinity}
where P(x) is the probability function calculated in part (a). The weighing function w(x) represents the contribution of chains with DP = x to the Mw calculation. The plot of w(x) as a function of x is shown below:
w(x) plot
(c) The number-average molecular weight Mn can be calculated by integrating over the DP distribution:
Mn = sum{k * w(k), k=0 to infinity}
We can approximate the sum as an integral:
Mn = integral{k * w(k) dk, k=0 to infinity}
Substituting w(x) from part (b), we get:
Mn = integral{x * P(x) dx / sum{k * P(k), k=0 to infinity}, x=0 to infinity}
sum{k * P(k), k=0 to infinity} = exp(lambda) = exp(-ln(1 - 0.985)) = 21.832
Substituting this value, we get:
Mn = integral{x * P(x) dx / 21.832, x=0 to infinity}
Performing the integration, we get:
Mn = lambda / (1 - exp(-lambda)) = 4.407
(d) The weight-averaged molecular weight Mw can be calculated by integrating over the DP distribution weighted by the number of polymer chains with that DP:
Mw = sum{M(x) * w(x), x=0 to infinity}
We can approximate the sum as an integral:
Mw = integral{M(x) * w(x) dx, x=0 to infinity}
Substituting M(x) = x * Mn, we get:
Mw = Mn * integral{x^2 * P(x) dx / sum{k * P(k), k=0 to infinity}, x=0 to infinity}
Substituting w(x) from part (b), we get:
Mw = Mn * integral{x^2 * P(x) dx / sum{k * x * P(k), k=0 to infinity}, x=0 to infinity}
sum{k * x * P(k), k=0 to infinity} = lambda^2
Substituting this value, we get:
Mw = Mn * integral{x^2 * P(x) dx / lambda^2, x=0 to infinity}
Performing the integration, we get:
Mw = Mn * (1 + lambda) / (1 - exp(-lambda)) = 13.863

if atmospheric pressure is 100 kpa, calculate the absolute and gauge pressure exerted on a diver 20 m below the surface of the sea in kpa. assume a specific gravity of 1.03 for seawater.
Absolute pressure = gauge pressure + atmospheric pressure
Gauge pressure = specific gravity x density of water x depth
Density of water = 1000 kg/m^3 for fresh water, 1030 kg/m^3 for seawater
Using these equations, the gauge pressure exerted on the diver 20 m below the surface of the sea is:
Gauge pressure = 1.03 x 1030 kg/m^3 x 20 m x 9.81 m/s^2 = 203 kPa
Adding this to the atmospheric pressure of 100 kPa, the absolute pressure exerted on the diver is:
Absolute pressure = 203 kPa + 100 kPa = 303 kPa
What is the formula for calculating absolute pressure?
The formula for calculating absolute pressure is Pabsolute = Pgauge + Patm, where Pabsolute is the total pressure acting on an object, Pgauge is the pressure measured by a gauge or instrument, and Patm is the atmospheric pressure at the location. In other words, absolute pressure is the sum of gauge pressure and atmospheric pressure. This formula is commonly used in fluid mechanics and thermodynamics to measure and calculate pressure in various systems, including liquids and gases.

A. Some are known as "nun" buoys
B. They are labeled with odd numbers
C. If it is lighted, the light color is green
D. Some are known as "can" buoys
According to the lateral system, the green, odd-numbered marks are placed on the port side of a channel while the red, even-numbered marks can be found on the starboard side. The buoy numbers rise as a ship moves upstream.
What do the inland rules say regarding red buoys?Black and white stripes on obstruction marks in inland waters indicate to ships where undersea dangers are. When flowing upstream, a green can buoy indicates passing to the right, and a red nun buoy indicates passing to the left.
What do the colours on the buoy mean?Typically, buoys are painted red, green, or a combination of the two colours. On buoys, the colours yellow, blue, white, and black are also permitted. A green buoy directs passing boaters.

the hermetic reciprocating compressor motor is essentially made of the same materials as an open type compressor motor. (T/F)
True. The materials used to construct an open type reciprocating compressor motor are also used to construct a hermetic reciprocating compressor motor.
What distinguishes a hermetic compressor from a reciprocating compressor?The reciprocating compressor has a displacement of 6.63m3/hr, whilst the hermetic scroll is a horizontal variant with a displacement of 2.08m3/hr. For tests at evaporation temperatures below 0°C, the refrigeration system served as the primary circuit and cooled a secondary glycol circuit.
Which compressor use an open motor as opposed to a hermetic one?An open motor is used in the rotary screw compressor rather than a hermetic one. A hermetic type reciprocating compressor's shell is typically thought of as being on the system's low pressure side.

Find the center of mass for a quarter of a uniform sphere in terms of the outside radius of the sphere, R.Express your answers in terms of R separated by commas.Learning Goal: To be able to find the centroid, center of mass, and center of gravity for lengths, areas, and volumes of simple, uniform objects. The centroid of an object is the object's geometric center. For objects of uniform composition, the centroid is also the object's center of mass.
Therefore, the coordinates of a quarter ring's center of mass in the first quadrant are (XCM,YCM) =(2R,2R).
Always consider a little mass when determining the center of mass. While the center of mass of a solid sphere is inside its body, it is outside the body in the case of a hollow sphere. By multiplying the system you're looking for the center of mass between by their positions, the center of mass can be computed. After that, add them all up and divide the result by the total of all the individual masses. Therefore, the coordinates of a quarter ring's center of mass in the first quadrant are (XCM,YCM)=(2R,2R).

True/False: Although C++ provides ample library functions to handle numeric values, we must write all of our own functions to manipulate character values.
False. C++ provides ample library functions to handle both numeric and character values, and programmers can choose to use either built-in functions or custom functions for their specific needs. The standard library includes functions for working with characters, strings, and other common data types.
What is the difference between numeric values and character values in C++ programming?Numeric values are values that represent numbers, such as integers or floating-point numbers, in C++ programming. They are used for mathematical computations, comparisons, and other operations that require numerical data. On the other hand, character values are values that represent characters or strings of text, such as letters, numbers, or symbols. They are used for text processing, input/output operations, and other tasks that involve manipulating or displaying textual data. Unlike numeric values, character values cannot be directly used in mathematical computations or comparisons, and must be converted to their corresponding ASCII codes or other numerical representations in order to be processed by the computer.
