Water at 50°F is pumped from a lake at 750 gpm through a length of 3-inch schedule 40 commercial steel pipe as shown below. The inlet to the pipe is eight feet below the surface of the lake. A 25-HP gasoline engine drives the pump and the pump has an efficiency of 80% What is the Reynolds number in the pipe? Is the flow laminar or turbulent? What is the head added to the water by the pump? What is the head loss due to pipe friction?

You have been asked to provide a design for a rapid mix tank at a water treatment plant which has an average water temperature of 60°F. The tank is to have a detention time (ta = HRT) of 1.5 seconds, a mixing intensity (G) of 1,428/second, and treats a flow (Q) of 9.4 mgd. Calculate the Motor Power (Pmotor, in HP) required to achieve the desired G value if the transfer efficiency is 80%. Provide your answer to the hundredths place (0.01). Be very careful with units (they need to cancel appropriately) and don't forget to report your answer in HP, not ft-Ib/sec).
Coming home after the end of the winter semester, you find that your family’s swimming pool has not be maintained well. In particular, it has no chlorine residual at all, and it is full of tree leaves. You buy a concentrated chlorine solution (1% as Cl2) and begin to meter it into the pool at a rate of 100 mL/hour. The pool has a volume of 200 m3. You also add new water, and remove in-pool water, at a rate of 3.785 L/minute. The chlorine reacts with the organic matter in the with a rate of 0.5/hour. How long will it take to get the Cl2 residual up to 1 mg/L if you add Cl2 continously.

In a test to determine the discharge coefficient of a 50 mm by 12.5 mm Venturi meter the total weight of water passing through the meter in 5.0 minutes was 3420 N.

Imagine a parcel of air that has a temperature of 40°C at the surface and a dew-point temperature of 20°C at the lifting condensation level. Assume that the environmental lapse rate is 8°C per 1000 meters, the dry adiabatic lapse rate is 10°C per 1000 meters, and the wet adiabatic lapse rate is 6°C/1000 meters. In Table C , record the environmental temperature, the parcel temperature, and the temperature difference (parcel temperature minus the environmental temperature), and then determine whether the atmosphere is stable or unstable at each height. a. What is the height of the lifting condensation level? b. Does this example describe absolute stability, absolute instability, or conditional instability? c. Would you forecast thunderstorms under these conditions?
Laminar flow of a liquid through a smooth 25 mm diameter pipe has a head loss of 1 m per meter length of the pipe with mean velocity of flow at 1.5 m/s. If the flow velocity is doubled, yet remaining in laminar flow, the resulting head loss per meter length of pipe will, nearly be ReplyForward
