A fixed-mass system contains mass, m = 1.0 kg of air. A thermodynamic process occurs from state one to state two, where T₁ = 300 °K, P₁ = 100 kPa; T₂ = 2700 °K, P₂ = 204.9953251 kPa. Determine S₂ - S₁ = m (S₂-S₁) in kJ / °K. Note: You are required to assume constant specific heats in this problem, with Cpo = 1.004 kJ/(°K * kg); for air, the gas constant is R = 0.287 kJ/(°K * kg).
Looking for velocity at the exit and mass flow rate. Show step by step solution please thank youu
An oil pump operating at steady state delivers oil at a rate of 12 lb/s through a 1-in-diameter exit pipe. The oil, which can be modeled as incompressible, has a density of 70 Ib/ft3 and experiences a pressure rise from inlet to exit of 40 Ib:/in?. There is no significant elevation difference between inlet and exit, and the inlet kinetic energy is negligible. Heat transfer between the pump and its surroundings is negligible, and there is no significant change in temperature as the oil passes through the pump. Determine the velocity of the oil at the exit of the pump, in ft/s, and the power required for the pump, in hp.
