Distilled water with a mass flowrate of 80,000 kg/h enters an exchanger at 35 °C ane leaves at 25 °C. The heat will be transferred to 140,000 kg/h of raw water coming fre a supply at 20°C. The baffles will be spaced 30.38 cm apart. A single shell and single tube pass is preferable. The tubes have 0.0254m inner and 0.0229m outer diameter and they are laid out on 1in. square pitch. Shell diameter is 38.735 cm. A pitch size of 3.175 cm and 0.635 cm clearance are selected. Calculate the length of the heat

Distilled water with a mass flowrate of 80,000 kg/h enters an exchanger at 35 °C and leaves at 25 °C. The heat will be transferred to 140,000 kg/h of raw water coming from a supply at 20°C. The baffles will be spaced 30.38 cm apart. A single shell and single tube pass is preferable. The tubes have 0.0254m inner and 0.0229m outer diameter and they are laid out on 1in. square pitch. Shell diameter is 38.735 cm. A pitch size of 3.175 cm and 0.635 cm clearance are selected. Calculate the length of the heat exchanger if the number of the tubes is 81.
