water at 20°C is pumped through a smooth 12-cm-diameter pipe 10 km long, at a flow rate of 75 m3/h. The inlet is fed by a pump at an absolute pressure of 2.4 MPa. The exit is at standard atmospheric pressure (101 kPa) and is 200 m higher. Calculate the frictional head loss Hf and compare it to the velocity head of the flow. B) A gate valve is used to control flow in the above system. What is the head loss due to the addition of the valve? What is the total head loss in the new system? state any assumptions made. for the value fully open k=0.17, 3/4 open k=0.9, 1/2 open k=4.5 and 1/4 open k=24

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
