Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.

Lukewarm water at 60 degree c in a storage tank is being pumped at 300 L/min from the tank. The line from the storage tank to the pump suction is 5 m of 2 inches Schedule 40 steelpipe, and it contains four (4) elbows. The discharge line after the pump is 50 m of 1.5 inches Schedule 40 steel pipe and contains a fully opened globe valve and two (2) elbows. The water was discharged to the households at 15 m above the water level in the storage tank. All elbows have a 90° angle. Calculate all frictional losses

Figure 8.18 shows a system used to spray polluted water into the air to increase the water's oxygen content and to cause volatile solvents in the water to vaporize. The pressure at point B just ahead of the nozzle must be 25.0 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.50 psig. The volume flow rate is 0.50 ft/s. The dynamic viscosity of the fluid is 4.0 x 105 lbs/ft². The specific gravity of the fluid is 1.026. Compute the power delivered by the pump to the fluid, considering friction energy loss in the discharge line.
