ASSIGNMENT ABO0UT THERMODYNAMICS
what is the heating value of oil in BTU/lbm at 27 degree API
select if true or false for the following questions 1. For a standard condenser in a refrigeration system, the thermal energy (in J) is equal to the mass (in kg) multiplied by the change in enthalpy across the condenser (in J/kg). 2. Consider a basic refrigeration cycle: Since it requires less work to compress a liquid than a vapor, the entire refrigeration process would work better if the compressor was replaced with a pump. All else being equal, increasing the mass-flow rate of refrigerant will increase the rate of heat transfer at the system’s evaporator. All of these (except, of course, the one labeled, “None of these.”) None of these.
