A gas mixture exists composed of 45% O2, 35% CO2 and 20% Ar on a molar basis. The pressure of the gas is 1 atm and the temperature is 50°F.
Determine:
a) The mass fraction of each component
b) The partial pressure of each component in (psi)
c) What is the molecular weight of the mixture?
d) How much volume in (ft3) would 10 lbm of this mixture occupy?
A river has a cross-section that is approximately a rectangle 10-ft deep and 50-feet wide. The average velocity is 1 ft/s. How many gallons per minute pass a given point? What is the average velocity (assuming steady flow) at a point downstream, wher..

A piston-cylinder arrangement initially contains water at P = 300 psia and T = 500 oF. The piston is moved to a final position where the volume is twice the initial volume. During the piston movement there is a heat transfer to the water in such a ..
The tank has a 180 mm inside diameter and a 12 mm wall thickness. Knowing that the tank contains compressed air under a pressure of 8 MPa, determine the magnitude T of the applied torque for which the maximum normal stress in the tank is 75 MPa.

A single phase step up transformer is used to transform 240VRMS to 2400VRMS. The transformer is operating at its rated power of 1kW (with purely resistive load), with transformer Reqp = 5, and a Xeqp = 4j, ignore the magnetising branch.
this would provide you with a set of Reynolds numbers. Next, using the integral method, determine the velocity profiles within the boundary layer to be followed by determination of the heat transfer coefficient values for your selected Reynolds numbe..
