A counterflow heat exchanger is designed to heat fuel oil from 45°C to 100°C while the heating fluid enters at 150°C and leaves at 115°C. Calculate the arithmetic mean temperature difference.
Using that information and this table For the average monthly rate of geothermal heat available, determine, for the real case: in a tabular format and show sample calculation for one month. the necessary monthly average mass flow rate (in kg/s) of the refrigerant that must be pumped through the heat exchanger to collect the thermal energy from the available geothermal hot water flow rate if the hot water was cooled by 5°C.

Detailed explanation: Two AES exchangers in series have trouble heating up a process stream from 50ᵒC to 90ᵒC, and cooling down a hot stream with the same flow rate from 110ᵒC to 70ᵒC. Luckily, there is an abandoned AES exchanger available that has four times the surface of the two existing exchangers, and even better, it has the right material and sufficiently high design P & T, and would fit on the plot space occupied by the existing exchangers. Is replacement a good idea?

Classifications of heat exchangers
(a) An Ocean Thermal Energy Converter (OTEC) pumps 200 m^3/s through a heat exchanger in which the temperature (expressed in Kelvins) drops by 1%. All the heat extracted is delivered to the ammonia boiler [11. The ammonia temperature. THT at turbine inlet is equal to the mean temperature of the water in the warm water heat exchanger minus 1 °K. The temperature, TCT, of the ammonia leaving the turbine is kept at 10 °C by the cooling effect of 250 m³/s of cold water. The efficiency of turbine/generator system is 90% of the Carnot efficiency of a heat engine working between THT and TCT . 12 MW of the produced electricity is used for pumping. Heat capacity of water is 4.2 MJ m³ K-1. Calculate the intake temperature of the warm water for the following cases: i) A total of 20 MW of electricity is available for sale? ii) The OTEC produces exactly equal to the amount of power needed for pumping?
