num. It also includes two ( 45^{circ} ) and four ( 90^{circ} ) regular screwed elbows, a fully open screwed gate valve, and a sharp exit into a tank. If the elevation of tank free surface is ( 180 mathrm{~m} ). A pump is to be installed for pumping water from pipe at a gauge pressure of ( 150 mathrm{kPa}=mathrm{P} 1 ) to upper tank and deliver ( 0.004 mathrm{~m}^{3} / mathrm{s} ) of water. Assume (
ho=1000 mathrm{~kg} / mathrm{m}^{3}, mu=0.001 mathrm{~kg} / mathrm{m} cdot mathrm{s} )
