Figure shows a cooling tower operating at steady state. Warm water from an air-conditioning unit enters at 49 °C with a mass flow rate of 0.5 kg/s. Dry air enters the tower at 21° C, 1 atm with a volumetric flow rate of 1.41 m/s. Because of evaporation within the tower, humid air exits at the top of the towver with a mass flow rate of 1.64 kg/s.

Step by step solution for mass flow, volumetric flow, and velocity please thank youu
A mixing vessel initially contains 4,485.43 lb of liquid fluid. The vessel is fitted with two inlet pipes, one delivering hot fluid at a mass flow rate of 0.635 lb/sec and the other delivering cold fluid at a mass flow rate of 0.836 lb/sec. Fluid exits through a single pipe at a mass flowrate of 1.144 lb/sec. Calculate the amount of fluid, in lb, in the tank after 44 minutes.
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.
ASEM 12/6/2015 Q1/ A stream of warm water is produced in a steady flow mixing process by combining 1.0 kg/s of cool water at 25 °C with 0.8 kg/s of hot water at 75 °C. During mixing, heat is lost to the surroundings at the rate of 30 kJ/s. What is the temperature of the warm water stream? Assume the specific heat of water constant at 4.18 kJ/kg.K.
Heat added in the process ?
Please answer asap.. I will rate helpful thankyou

Air at 1 bar, 27 °C, with a volumetric flow rate of 40 m³/min enters the non-mixing counterflow heat exchanger part of an air-conditioning system. This air exits the heat exchanger at 0.95 bar and 17 °C. The cooling of this air is done by a stream of refrigerant R-134a that enters the heat exchanger at 5 bar with a quality of 0.3 and exits at 5 bar and 20 °C. Determine the overall rate of entropy production during this process, in kW. The overall heat exchanger is insulated. The operation is steady state, and the effects of potential and kinetic energy are negligible.
