Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

A square bottomed tank measures 25*25*160cm and is positioned with the bottom of the tank 1m above sea level and at 20degreesC. The tank is 90% filled with water and 10% air. A water inlet enters the centre of the tank of 10mm diameter, and no other inlet or outlet is open within the tank. A pump drives water at a starting rate of 450ml/min at 0 Pa lowering to 350ml/min as the pressure increases to 800 kPa. The pump and tank are connected by a 10mm diameter pipe with k=0.15 for all fittings and tubing. It should be assumed this is the maximum flow and pressure provided by the pump. The pump will stop instantaneously once the pressure reaches 800kPa. The relationship between flow and pressure from the pump should be assumed linear. What will be the volume of compressed air inside the tank and how long will it take to fill?
