(b) A pump is to be installed to lift water from a low level tank to a high level tank as shown in Figure Q2 at a rate of 120m3/hr. The friction factor (2) of the pipe is 0.024 and its length is 40m. Assuming the density of water is 1000kg/m3 answer the following: (i) Calculate the equivalent length of the fittings [3 marks] (ii) Calculate the total equivalent length of pipe & fittings [1 marks] (iii) Calculate the pump head required for this system [6 marks] (iv) Calculate the Fluid Power developed by the pump [2 marks] (v) If the mechanical efficiency of the pump is 90% calculate the required shaft power [1 marks] (vi) Using a sketch, indicate the position(s) within the system where you would expect to install a non return (check) valve.
