A person is attempting to start a 20hp diesel engine with a hand crank. The distance from the handle to the center of rotation is 12 inches. The person is able to apply 25 lbf tangent to the circular path of the handle. The crank rotates at 2 rounds per second. How much power (Btu/min and hp) is the person providing?

Determine the flow velocities at the inlet and exit sections of an

inclined tapering pipe using fluid flow theory and given pressure

readings and flow rates.

There is a sloping pipeline that has one end 1.35 m higher than the

other. The pipe section tapers from 0.95 m diameter at the top end to

0.44m diameter at the lower end. The difference in pressure between

the two sections is 12.35kPa, with pressure being greater at higher

level.

Your task is to determine the inlet and exit velocities and the

volume

flow rate of the inclined pipe.

In water and wastewater treatment processes a filtration device may be used to remove water from the sludge formed by a precipitation reaction. The initial concentration of sludge from a softening reaction (Chapter 4) is 3 2 percent (20,000 mg/L) and the volume of sludge is 100 m. After filtra - tion the sludge solids concentration is 35 percent. Assume that the sludge does not change density during filtration, and that liquid removed from the sludge contains no sludge. Using the mass balance method, determine the volume of sludge after filtration.
