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.

4.30 Refrigerant 134a enters a heat exchanger operating ai steady state as a superheated vapour at 10 bars. 60°C. where it is cooled and condensed to saturated liquid at 10 bars. The mass flow rate of the refrigerant is 10 kg/min. A separate stream of air enters the heat exchanger at 37°C with a mass flow rate of 80 kg/min. Ignoring heat transfer from the outside of the heat exchanger and neglecting kinetic and potential energy effects, determine the exit air temperature, in °C.
Which of the following is incorrect about the overall energy balance and mechanical energy balance in fluid flow phenomena?A. The former only accounts the first law of thermodynamics while the latter includes the second.B. The former only accounts the work brought by changes in the volume while the latter includes the Δ(PV) work.C. The enthalpy of the system for both balance is the sum of the changes in the internal energy and the reversible work at constant pressure.D. The former is not often used to evaluate a system with changing pressure unlike the latter.

1. A 5,000 kg/min of water at 35°C enters a cooling tower where it is to be cooled to 20 °C. The energy is to be exchanged with atmospheric air entering the unit at 16°C and leaving the unit at 32°C. The air enters at 35% RH and leaves at 80% RH: If all process are assumed to occur at atmospheric pressure, determine the percentage of total water flow that is makeup water. 2. A 45 GPM of water enters a cooling tower at 50°C. Atmospheric air at 14°C and 50% RH enters the tower at 3.5 m and leaves at 25°C saturated. Determine the volume of water that leaves the tower.
