Two vessels A and B of different sizes are connected by a pipe with a valve. Vessel A contains 142 L of air at 2,767.92 kPa, 93.330C. Vessel B, of unknown volume, contains air at 68.95 kPa, 4.440C. The valve is opened and, when the properties have been determined, it is found that pm = 1378.96 kPa, tm = 43.330C. What is the volume of vessel B?
Compress 6 kg/s of CO2 gas polytropically (pV1.2 = C) from p1 = 103.4 kPa, t1 = 50°C to t2 = 227°C. Assuming ideal gas action, find p2, W, Q, ΔS (a) as nonflow, (b) as a steadyflow process where ΔP=0 and ΔK=0.
A gas cylinder with interior volume 11.6 L holds compressed air at 17.4 MPa. The cylinder is joined by a hose of negligible volume to a second cylinder that’s been pumped down to vacuum. When the valve on the full cylinder is opened, the air expands to fill the entire system, all the while maintaining a constant temperature. If the energy that becomes unavailable to do work is 171.8 kJ, what’s the volume of the second cylinder (L)?
