12.54 Air at 12°C, 1 atm, and 40% relative humidity enters a heat exchanger with a volumetric flow rate of 1 m'/s. A separate stream of dry air enters at 280°C, 1 atm with a mass flow rate of 0.875 kg/s and exits at 220°C. Neglecting heat transfer between the heat exchanger and its surroundings, pressure drops of ach stream, and kinetic and potential energy effects, determine (a) the temperature of the exiting moist air, in °C
The figure below provides steady-state data for a throttling valve in series with a heat exchanger.
The figure below provides steady-state data for a throttling valve in series with a heat exchanger. Saturated liquid Refrigerant 134a enters the valve at a pressure of 9 bar and is throttled to a pressure of p2 2 bar. The refrigerant then enters the heat exchanger, exiting at a temperature of 10°C with no significant decrease in pressure. In a separate stream, liquid water at 1 bar enters the heat exchanger at a temperature of 25°C with a mass flow...

Hot air enters a heat exchanger at 350°C and exits at (149°C. The heat extracted is used to boil (0.263) kg/s of 100°C water (from saturated liquid to saturated steam). The heat exchanger is a single-shell shell-and-tube heat exchanger with two tube passes. The overall heat transfer coefficient for the hot side is 240 W/(m2°C). Assume a constant specific heat for air of Cp = 1.005 kJ/(kgC). The pressure of the hot air and the boiling water is P =...

An adiabatic heat exchanger is one for which no heat is exchanged with the surroundings. All of the heat lost by the hot stream is transferred to the cold stream in this adiabatic process. In a proposed process, propane gas enters a continuous adiabatic heat exchanger at 45 °C and 265 kPa and exits at 255 °C. Superheated steam at 300 °C and 7.0 bar enters the exchanger flowing countercurrently to the propane and exits as a saturated liquid at...

(40 pts) Shell-and-Tube Heat Exchanger to make Jell-O Cups A counter-current shell-and-tube heat exchanger is used to heat Jell-O solution (water + gelatin) using saturated steam on the shell side. Jell-O solution must be heated to at least 80 oC, poured into individual plastic cups, and then cooled to make the solid Jell-O cups. The Jell-O solution is heated with steam that enters the shell at 2.0 bar (Tsteam = 120oC) and exits as a saturated liquid. At this temperature...
