A one-shell and two-tube type heat exchanger has an overall heat transfer coefficient of 300 Btu/h·ft2·°F. The shell side fluid has a heat capacity rate of 20,000 Btu/h·°F, while the tube side fluid has a heat capacity rate of 40,000 Btu/h·°F. The inlet temperatures on the shell side and tube side are 200°F and 90°F, respectively. If the total heat transfer area is 100 ft2, determine (a) the heat transfer effectiveness and (b) the actual heat transfer rate in the heat exchanger.
A flow calorimeter is an apparatus used to measure the specific heat of a liquid. The technique of flow calorimetry involves measuring the temperature difference between the input and output points of a flowing stream of the liquid while energy is added by heat at a known rate. A liquid of density 900 kg/m3 flows through the calorimeter with volume flow rate of 2.00 L/min. At steady state, a temperature difference 3.50°C is established between the input and output points when energy is supplied at the rate of 200 W.What is the specific heat of the liquid?
