Consider the section of water distribution piping shown below. Ignoring minor losses, find the flow rate in pipe CB, the total energy at point C, and the pressure at point D. The water temperature is 10°C. C-D: 400m @ 325mm ø D-B: 400m @ 325mm (C=140,k, =1.5x106 m) (C=140,k=1.5x10“ m) Demand = 0.78m³/s C D ZD= 50m Ев 80m zc=45m ZB= 40m A-B: 3000m @ 400mm ở E = 141m (C=120, k =5.3x10+ m) ZA = 60m Flow rate in pipe CB (in m3/s)? Total energy at C (in m)? Pressure at D (kPa)? A-C: 2200m @500mm (C=120, k =5.3x10+ m)
An elevator has a rated capacity of 2200 lb. It can transport people at the rated capacity between the first and the fifth floors, with a vertical distance of 15 ft between each floor, in 7 s. Estimate the power requirement for such an elevator.
Calculate the thermal resistance due to convection for the following situations: a. warm water with h = 200 W/m2 K b. warm air with h = 10 W/m2 K c. warm moving air (windy situation) h = 30 W/m2 K
Suppose a wet mixture of old bread, leaves, and soil is placed in a pile 1 m tall, and a long thermometer is struck in the middle of the pile. Every other day. the pile is aerated by throwing the mixture into a new pile. Draw a graph showing the temperature in the pile during the first two weeks and explain why these temperature changes occurs.
Compare the masses and volumes of water, concrete, sand, and wood needed to store 106 Btu of heat if the operating temperatures are Tc = 85F and Th = 180F. In each case, calculate the edge length of a square storage unit with a height of 8 ft.
You serve as the president of XYZ corporation, which is an energy intensive manufacturing operation. You have four boilers to produce steam and electricity for your operations. One is a semi-suspension fired boiler with a capacity of 100 tons of coal per hour. The boiler can also burn supplemental fuel such as coconut or macadamia nut shells. The other three boilers arc peaking units and burn fuel oil. The City of Podunk has approached you about the possibility of burning solid waste as a supplemental fuel. As the president of the XYZ Corporation, you need to develop answers to many political, social, and technical questions before you make a commitment to the city. a. What specific questions would you ask your own power plant engineer about the possibility of accepting Podunk’s MSW? b. What specific additional data would you need from the city before you discuss this further?
