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.

The below figure shows a pump that transfers a steady stream of 35 API crude oil from an oil
tanker to a refinery storage tank, both free surfaces being open to the atmosphere. The
effective length-including fittings-of the commercial steel pipe is 6,000 ft. The discharge
at point 4 is 200 ft above the pump exit, which is level with the free surface of oil in the
tanker. However, because of an intervening hill, point 3 is at a higher altitude than point 4.
Losses between points 1 and 2 may be ignored.

Question #2 Calculate the Net Positive Suction Head (NPSH) for a pump handling 100,000 kg/hr flow of water coming from an atmospheric storage tank. The water temperature can be taken as 25°C.

3. Petrol is drained from a tank X to tank Y via pipeline A-B (see figure Q3). A pump is then used to pump the petrol from tank Y to tank Z via pipeline C-D. Pipe lengths, diameters and relative heights of the pump and tank levels are as shown in figure Q3. The density of the petrol is 760 kg/m³ and the Fanning friction factor (f) for all the pipes is 0.0075. • For pipe A-B the entrance loss at A is 0.5 • For pipe C-D the entrance loss at C is 0.5 u² • All valve losses are 0.2 each, 2g Neglect any entrance or exit head losses at the pump and all other pipeline component losses.

A fire starts in an apartment building in downtown Boston. When the firefighters arrive, they immediately get to work putting out the fire using a fire hose. The water for the fire hose is provided by a fire hydrant at ground level. Assume that the velocity of the liquid coming from the fire hydrant is 1.6 m/s, and that the pressure at the hose nozzle is atmospheric pressure (101000 Pa). a. The firefighters start with the ground floor, so there is no change in height between the fire hydrant and the hose nozzle. If the velocity of the water coming out of the nozzle is 12.8 m/s, find the pressure at the fire hydrant in units of Pa. b. After the ground floor fire is put out, another fire is spotted on another floor. A firefighter carrying the hose is lifted on a platform to the same height as the fire, which is 44.35 m above the ground. Assuming that the pressure found in part a) remains constant, what would be the new velocity of the water coming out of the nozzle at this new height?
The task is to to transfer the fluid from the source towards the tank (TANK A) lying on an elevated platform as shown. The goal is to fill up that 16.49 m by 2.23 m by 6.36 m tank (TANK A) within 11.5 mins (from empty to full). Your budget is limited to 605,000 pesos. Head loss on pipe due to friction is 1.23 meters per 1 meter of pipe. Because it's Fluid Machinery and not Engineering Economics, it's ok for your design to exceed the budget BUT YOU HAVE TO JUSTIFY IT.
