Task 1 Design a pump that will develop at least 2.75bar at a flow rate of 19.0 kg/s of water.
What combination of pump size, motor speed, and impeller diameter from the pump characteristics would be the best for this application?
• State reasons for the choice make on pump size, motor speed and impeller diameter.
• What are the purnp efficiency, motor horsepower and torque requirement. and NPSH for the chosen pump at these operating conditions?
Task 2 Carry out thermal analysis of a Shell and Tube Heat Exchanger to be used as a Crude Oil Cooler in Petroleum industry. A 120 kg/s of crude Al enters the shell Ade of the heat exchanger at 100°C and leaves at 65°C. The coolant to be used is Aty water entering the tube side at 20°C .th a flow rate of 65kg/s. Shell side and tube side pressure drops is limited to 150kPa and 50kPa respectively.
• State reasons for the choice make on dimensional details related to shell and tube sides.
• What is the baffle details and number of passes recommend. for this application?
• Calculate heat transfer coefficients at shell and tube sides for the designed Heat exchanger.
