The sketch 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 6. water to vaporize. The pressure at B of the nozzle must be 25 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.5 psig. The volume flow rate is 0.5 ft3/s. The dynamic viscosity of the fluid is 4.0 x 10 Ib-s/ft?. The specific gravity of the fluid...

Water is supplied at a rate of 100 ft? 5-1, pressure of 50 psi to a turbine through a 5 ft 2 cross-sectional area pipe. The exit conditions are: Water discharges through a pipe of cross-sectional areas 2 ft2 into the atmosphere. The turbine develops a power of 500 hp. The total head loss in this system is 10ft. Assume density of water is 62.8 lbf/m3 Part 1: The velocity with which waters discharges into the atmosphere is ft s-1...

Problem 5: The 28-in-diameter pump in the Figure at 1170 r/min is used to pump water at 20°C through a piping system at 14,000 gal/min. (a) Determine the required brake horsepower. The average friction factor is 0.018. (b) If there is 65 ft of 12-in-diameter pipe upstream of the pump, how far below the surface should the pump inlet be placed to avoid cavitation? Given that the water at 20 °C has a specific weight of 62.4 lbf/ft and vapor...

The figure below shows a condenser/cooling tower pipe system needed to remove heat from a water cooled refrigeration condenser and reject the heat to the atmosphere. The amount of heat to be rejected to the atmosphere is 480,000 Btu/hr. The water enters the condenser at 85"F, and the temperature rise of the water through the condenser is 10°F. The total length of the piping in the system is 60 ft. Fittings are as shown. Assume bends to be as shown...

Objective To determine the force generated by a jet of water striking on a surface Description of apparatus The supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate, Hemispherical Cup, Conical Plate or 30° Angled Plate. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which the...
