Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Carbon dioxide is being pumped through a smooth pipe at the rate of 3×10-4 kmol/sec for a distance of 2000 m. Ifthe line is isothermal at 323.15 K and the pressure at the entry point is 750 ×103 Pa and at the exit point is 430×103 Pa, what diameter should the pipe has to ensure that the CO2 will be delivered to the end point with the pressure drop experienced. The viscosity of CO2 at 323.15 K is 1.45×10-5kg/m.s. One trial is sufficient given you tell us how you will proceed to achieve an accurate diameter estimate. Hint: for your initial guess, use D in the range of 0.01-0.02 m.

Spherical particles of density 2000 kg/m3 and in the size range 20– 100 mm are fed continuously into a stream of water (density, 1000 kg/m3 and viscosity, 0.001 Pa s) flowing upwards in a vertical, large diameter pipe. You would like the velocity of the water be such that no particles greater than 50 mm are carried upward with the water.

Oil that has a density of 880 kg/m3 flows under a head of 30 m. The pipe that the oil flows through is 3000 m long and 0.35 m in diameter. Due to the cooling along the span of the pipe the viscosity changes, this may be taken as 0.57 kg/m-s over the first 1500 m and 1.14 kg/m-s over the second 1500 m. Confirm that laminar flow conditions exist and calculate the flow in dm³/s. Neglect entry and exit losses.
