(a) (b) If the air is allowed to leak out of the tank so that the constant at 50°C, what is the rate of air flow out of the tank? 1.4. A centrifugal air compressor has an air intake of 1.2 kg/min. The pressure and tem- perature conditions are inlet, 100 kPa, 0°C, and outlet, 200 kPa, 50°C. If the heat losses are negligibly small, what is the power input to the compressor? From tables of air properties, the internal energy and specific volume at the inlet and exit are: u = 330.49 kJ/kg, V₁ = 0.7841 m³/kg U₂ = 366.26 kJ/kg, V₂ = 0.464 m³/kg What would be the answer if air were considered a perfect gas with constant specific heats? 3 tank contains air at 0 1 MPa and 20°C A high-pressure line is connected to
