Methane, ch4, has reduced pressure p, 0.7 and reduced temperature tr = 1.1 the critical temperature of methane is 190.4 [k] and the critical pressure of methane is 4.60 [mpa] find: a)- z, the compressibility b)- v, the specific volume, using pv=zrt

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
