Beer with a specific gravity of 1.05 and viscosity of 1.5 mPa.s and having 2% solids is clarified at a rate of 60 gallons per hour in a bowl centrifuge. The density of solids is 1180 kg/m3. The operating volume of the bowl is 25 gallons and operating at a speed of 10,000 rpm. The bowl has a diameter of 4 and 3/16” and outlet diameter is 1.5”. Calculate the effect on feed rate with an increase in the bowl speed to 12,000 rpm and the minimum particle size that can be removed at this higher speed. All conditions except the bowl speed remains the same

As shown in Figure D, three water reservoirs are connected by three pipes. The diameters in each pipe is 1 ft and the Fanning friction factor in each pipe is 0.02. The effective lengths of each pipe are given in the Figure along with other relevant data. Determine the flow rate into or out of each reservoir as well as the Reynolds number in each pipe. (Hint: Start the computations by assuming that the water flows into reservoir B).

The _______ air compressors are used for delivering large volume of air at a medium pressure a.Rotary b.Axial c.Centrifugal d.Reciprocating

It is desired to have a laminar flow for the piping system shown below. The fluid flowing in the piping system is air at 70 °C. (Note: You must use the physical data from Perry's Handbook) a) Calculate the maximum allowable bulk velocity in m/s for pipes 1, 2, and 3 that will satisfy the statement above. The velocities obtained must satisfy the continuity equation. b) Calculate the Reynolds number of each pipe using the velocity values obtained earlier. c) Calculate the mass flow rate of the system (in kg/min). 3. 2 12-in. pipe 2-in. pipe 3-in. pipe 1/2-in. pipe

A ventilation opening in a room is 2 feet by 3 feet.  Air flow out of the opening is measured at 75 feet per minute.  Calculate the CFM rate.

While performing a leak off test the surface pressure at leak off was 940 psi. The casing shoe was at a true vertical depth of 5010 ft and a mud weight of 10.2 ppg was used to conduct the test.

How much work must be input by the paddle wheel below to raise the piston 5 cm. The initial temperature is 100°F.

Water is pumped at a rate of 10.0 kg/s from a point 200.0 m below the earth's surface to a point 100.0 m above the ground level. Calculate the rate of change in potential energy.
