A shell and tube heat exchanger is designed as a counter to cool a mass flow rate of 60 kg/h of engine oil (cp = 1060 J/kg oC) from 300oC to 150oC. The cooling water, cp = 4182 J/kgoC, enters the tube side (Length is 1.75 m and Outer diameter is 2.54 cm) at a temperature of 20oC. If the overall heat transfer coefficient, U, is 10.83 W/m2o C and the Capacity Ratio of the Heat Exchanger is 2.4, calculate the following: a)The heat transfer rate,b)The mass flow rate of the cooling water in the units of (kg/h),C)The surface area of the heat exchanger,

A shell and tube heat exchanger is designed as a counter flow type. Water (cp = 4182 J/kg.oC)enters the shell side at 30 oC with a mass flow rate of 12.5 kg/s. A mass flow rate of 19.5 kg/s of engine oil (cp = 1060 J/kg.oC), enters the tube side at 300 oC. Each tube is having an inner diameter of 36 mm and a wall thickness of 2 mm, and a length of 3 m. If the heat exchanger effectiveness is60 %, calculate the following: a) The tube side surface area if the overall heat transfer coefficient is 1586 W/m2. oC,b) The number of tubes used in the heat exchanger,

A body-and-tube heat exchanger with 2 shells and 8 tubes is used to heat ethyl alcohol (cp=2670J/kg.°C) from 25 °C to 70 °C with a flow rate of 2.1 kg/s in pipes with a diameter of 3 cm. Heating It is made with water that enters the body at 95 °C and leaves at 60 °C (cp=4190J/kg.°C). If the total heat transfer coefficient is 800 W/m2.°C, calculate the total length of the heat exchanger using the Ɛ-NTU method.
