Q3- A heat exchanger with one shell pass and 8 tube passes. The hot water flow in the tube side. It used to heat oil on the shell side. The tube material is copper and has inner and outer radii of 8 and 12 mm and a length per pass of 5 m. The water enters at 95 °C and leaves at 40 °C with a mass flow rate of 0.3 kg/s. Inlet and outlet temperatures of oil are 15 °C and 35 °C. Determine: a- LMTD b- Heat transfer Rate c- Effectiveness d- The inner and shell convection heat transfer coefficients.
