Water from a reservoir flowing through a non rigid 600mm diameter pipe with a velocity of 2.m/s is completely stopped by a closure of a valve situated 1050m from the reservoir. The pipe thickness is 18mm. Bulk modulus of elasticity of water is 2000MPa and modulus of elasticity of steel is 200000MPa. A.) Compute the velocity of soundwave Choices: 1724.47 1442.47 1224.74 2441.74 B.) Determine the pressure due to instantaneous closure (KPa) Choices: 2449.49 4229.94 2994.94 4922.49 C.)Determine the pressure due to a closure that takes place in 5 seconds. in KPa Choices: 408 804 840 480 Note:please help me in the sample problem and please base ypur answer on the given choices thank you

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
