Refrigerant 134a enters an insulated diffuser as a saturated vapor at 80°F with a velocity of 1400 ft/s. The inlet area is 1.4 in?. At the exit, the pressure is 400 lb;/in? and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be neglected. Determine the mass flow rate, in Ib/s, and the exit temperature, in °F.
Thermodynamics: Please show me how to solve the following practice problems in step by step solution (Thank you so much!)
A mixing vessel initially contains 3,936.2 lb of liquid fluid. The vessel is fitted with two inlet pipes, one delivering hot fluid at a mass flow rate of 0.216 Ib/sec and the other delivering cold fluid at a mass flow rate of 0.94 lb/sec. Fluid exits through a single pipe at a mass flow rate of 1.268 Ib/sec. Calculate the amount of fluid, in lb, in the tank after 24 minutes.
A reheat cycle with two stages of reheating is executed with steam expanding initially from 25 MPa and 600 °C. The two reheater pressures are 4 MPa and 1 MPa, and the steam leaves each reheater at 600 °C. Condensation occurs at 40°C. For 1 kg/s of steam, what is QA in kW? Remember, 1. For values taken from the steam tables: Use them as is, do not round off. 2. For values obtained by interpolation and final answers obtained by solving, use FOUR (4) decimal places. 3. Use the steam tables provided
5. Air enters a compressor at a rate of 0.5 Kgs¹ with a velocity of 6.4 ms', specific volume 0.85 m³Kg¹ and a pressure of 1 bar. It leaves the compressor at a pressure of 6.9 bar with a specific volume of 0.16 m³Kg¹ and a velocity of 4.7 ms¹. The internal energy of the air at exit is greater than that at entry by 85 KJKg'. The compressor is fitted with a cooling system which removes heat at a rate of 60 KJs¹. Calculate the power required to drive the compressor and the cross- sectional areas of the inlet and outlet pipes.
