Question

Problem 4 Carbon dioxide passes point A in a 3-inch diameter pipe at a velocity of 15 ft/s. The gage pressure at A is 30 psi and the temperature is 70°F. At point B downstream, the pressure is 20 psi and the temperature is 90°F. Calculate the following: (a) specific weight at A and at B (use ideal gas law), (b) mass flowrate at A and at B, (c) volumetric flowrate at A and at B, and (d) velocity at B.

Step 1

(a) To calculate the specific weight at point A and B, we can use the ideal gas law equation: PV = nRT Where: P = pressure V = volume n = number of moles R = ideal gas constant T = temperature First, let's calculate the number of moles at point A: PV = nRT (30 Show more…
