Flow through Pipes and Liquids in relative equilibrium - Assignment

It consists of typed Assignment on Flow through Pipes and Liquid in relative equilibrium. It is shared to me by a student studying at NMIMS, Mumbai and I thought of uploading it here so that the students of first and second-year engineering would benefit a lot from it. Thank You! Enjoy learning. When a sudden contraction from 60 cm diameter to 30 cm diameter is introduced in a horizontal pipeline, the pressure drops from 100kPa at the upstream to 80kPa on the downstream. Assuming a coefficient of contraction of 0.65, (i) estimate the flow rate in the pipe and (ii) the loss of head due to contraction
