I need help with some review problems! thank you Steam at 440K, 100kPa, with a mass flow rate of 0.164kg/s enters an adiabatic mixing chamber and mixes with 10.00 kg/s of water entering at 325 K, 100 kPa to produce an exit stream of water at 100 kPa. Assuming a steady state steady flow process, USE THE ATTACHED H2O TABLES to determine: a) The mass flow rate (kg/s) at the exit.b) The water exit temperature (K).c) The exit velocity (m/s) if the circular exit pipe diameter is 0.03m.

Hot water at 400kPa, 150 deg Celsius is fed to a throttle at a rate of 1.5kg/s and exits at 200kPa. After leaving the throttle, the resulting mixture enters a chamber where the vapor leaves from the top at 200kPa and the liquid leaves from the bottom at 200kPa. What is the mass flow rate of each of the two exit flows?
