WebApr 6, 2024 · The net refrigeration effect, or evaporator cooling, is the difference in specific enthalpy of the evaporator, or, 175.41- 109.3 = 66.11 Btu per pound of refrigerant. Three tons of cooling is 600 Btu/minute. Divide 600 by 66.11 and you get the refrigerant flow of 600 / 66.11 = 9 pounds per minute of refrigerant flow required to meet the ... http://ch301.cm.utexas.edu/thermo/enthalpy/enthalpy-all.php
WebApr 6, 2024 · Enthalpy is the quantity of heat in a system. This heat is utilized in the occurrence of a process. Any heat-related system is called a thermodynamic system, so Enthalpy is a thermodynamic quantity. Besides, it should be noted that any system comprises multiple participants. Each of these participants has its pressure and volume. Webmore about degrees Celsius and degrees Kelvin. A calorie is defined as the amount of heat required to change the temperature of one gram of liquid water by one degree Celsius (or one degree Kelvin). 1 cal = 4.184 J. 1 J = 1 Ws. = (1 Ws) (1/3600 h/s) = 2.78 10-4 Wh.
