A steel shaft 3 m long is transmitting 1 MW at 240 rev/min. The working conditions to be satisfied by the shaft are: (a) that the shaft must not twist more than 0.02 radian on a length of 10 diameters; (b) that the working stress must not exceed 60 MN/m2. If the modulus of rigidity of steel is 80 GN/m2 what is (i) the diameter of the shaft required (ii) the actual working stress; (iii) the angle of twist of the 3 m length?

The old Hydraulics laboratory in Mechanical Engineering used a roof tank tosupply apparatus with water at a nearly constant head. The water wascollected in an under floor sump, and then pumped back to the roof tankafter the experiment. The flow rate was 10 litre s-1. The tank was 6m abovethe sump, and the length of the pipe route was 15 m. The old 6” pipes arenow heavily corroded (k = 7.5 mm). The old pump has been scrapped. Whathead ΔH would be specified for a pump to restore the system using the oldpipes? What would the pump power be? If the pipes were replaced with 150mm diameter PVC pipes, what pump ΔH would be required?
