QUESTION 3 You are asked to select a new centrifugal pump for the piping system shown below that will be used to deliver 0.0233 m³/s of hot (50 °C) water from the storage tank into the reactor. The entire piping system is constructed from 10 cm internal diameter, wrought iron pipe. A gate valve is located between the pump outlet and reactor inlet. The storage tank and reactor are both closed vessels but they are vented to maintain atmospheric pressure above the liquid level. A local equipment supplier sends you the performance curves for four different pumps that are labelled 'Pump A', 'Pump B', 'Pump C', and 'Pump D'- the curves are shown on pages 7 & 8. Data: Water at 50 °C: Storage Tank density=988 kg/m³ viscosity = 0.000547 Pa's vapour pressure = 12.3 kPa 4 m ↓ 2 m ↑ L Reactor a. Calculate the available Net Positive Suction Head (NPSH). Note that previous experiments showed that the total head loss for the piping section between the storage tank and the pump, H has been determined…
In an experiment, the weight density of an oil is 8876 N/m3 and its mass is 8.4 kg/m3, then its volume is m3 O 9.04791 O 90.47910 O 0.00928 0.00010
Take the fluid densities of air, water, oil and mercury to be 1.299 kg/m3, 1000 kg/m3, 850 kg/m3 and 13,500 kg/m3 respectively.

Q2 a) Consider the wing of an aircraft as a flat plate of 25 m length in the flow direction (Figure 2). The plane is moving at 100 m/s in air that is at a pressure of 0.7 bar and a temperature of 10°C. The top surface of the wing absorbs solar radiation at a rate of 800 W/m2. Assume the wing to be of solid construction and to have a single, uniform temperature. Estimate the steady-state temperature of the wing. Refer Table A-15 for air thermophysical properties.
