Calculate the fan power if the average pressure drop m 0.6 in, H2O, and the fan/motor efficiency is 70%. An ESP must treat 800,000 aefra with 99% efficiency.

A fixed-bed carbon adsorption system consisting of two 8-foot-deep beds containing 6 x 16 mesh carbon operates at a superficial gas velocity of 60 ft/min. Specify the horsepower of the fan motor for the 15,000-cfm system if the total pressure drop across the system excluding the pressure drop across the bed is 5 in H2O.

An ESP must treat 300,000 acfm with 99% efficiency.  Estimate the cost of this ESP (f.o.b. Manufacturer and TIC), both in 1998 dollars.   2. Calculate the fan power if the average pressure drop is 0.6 in. H2O, and the fan/motor efficiency is 70%.

Q3: Find the drain spacing between two drains using Hooghoudt Equation if you know that the recharge is 5 (cm/day), depth of water table from drain level 1.2m, depth of impervious layer is 20m, the hydraulic conductivity for the layer above the drain is 2(m/day), while the one for the layer below the drain is 0.7(m/day). Note: use only two trials

Calculate the required pipe diameter to avoid cavitation, if the pump deliversQ = 30US gallon/min water from a closed tank, where the pressure (above thewater level) is p = 40kPa. The equivalent length of the smoothened concretepipe on the suction side is 12m while the suction flange of the pump is 8m belowthe water level. The vapour pressure at the given water temperature is 2.8kPa.The required net positive suction head is NPSHr = 3.2m.   Show the complete solution and units being cancelled.

Include a free body diagram The water level in a tank is 34 ft above the ground. A hose is connected to the bottom of the tank at the ground level and the nozzle at the end of the hose is pointed straight up. The tank cover is airtight, but the pressure over the water surface is unkown. Determine the minimum tank air pressure (gage) that will cause a water stream from the nozzle to rise 72 ft from the ground.A. 13.5 psiB. 15.5 psiC. 16.5 psiD. 14.4 psi

In a pump test the suction pressure at the pump inlet is -28.00 kPa below atmospheric pressure. The discharge pressure at a point 960 mm above the inlet is 525 kPa. Hydraulic steel tubing is used for both the suction (inlet) and discharge (outlet) lines with 80 mm OD × 2.8 mm wall. Required If the volume flow rate of water is 88 L/min, calculate the power delivered by the pump to the water in kW, to the nearest 1000th. Discharge pipe Suction pipe Flow Pump |||+

Water in a 35-cm dia. has 62°F temperature and the discharge is measured as 0.3 m/s and the pressure of 200 Pa. The elevation of the center of the pipe is at 10.5 m a.m.s.l. What is the total energy of the flow? Is the flow laminar or turbulent? Viscosities of Water and Air

QUESTION 1 Compute the resulting pressure in kPa after a "real" diffuser in which the energy loss due to sudden enlargement is considered for the flow of water at 25°C from a 36 mm OD x 2.0 mm wall copper tube to an 85 mm OD x 2.5 mm wall copper tube, the pipes are the same elevation. The volume flow rate is 150 L/min and the pressure before the enlargement is 501.448 kPa.

A galvanized-iron pipe (ε = 0.0005 ft) is to carry air at standard temperature and pressure at a rate of 2.0 ft3/s. The pressure drop is to be no more than 0.50 psi per 100 ft. Design the pipe diameter.
