Question 3 (a) Water flows through a horizontal pipeline of constant 400 mm diameter in a water treatment plant. The pipe bends through a 70° angle. In order to design a thrust block for the bend, calculate the magnitude and line of action of the force exerted by the water on the pipe. The discharge through the pipe is 0.4 m/s. The water pressure at the inlet is equivalent to 22 m head of water. [10 marks] (b) Oil of...

(40 points) Engine oil flows at a rate of 1 kg/s through a 5-mm diameter smooth straight tube. The oil has an inlet temperature of 47°C and it is desired to heat the oil to a mean temperature of 87°C at the exit of the tube. The surface of the tube is maintained at 150°C. Assuming the flow is fully developed both hydrodynamically and thermally, determine the required length of the tube. Note: by calculating Reynolds number at the entrance...
