A pipeline with a pump carrying a 50 L/s discharge leads to a nozzle as shown. If the 180 mm diameter pipe is made of cast iron while the 120 mm diameter pipe is made of commercial steel. Determine the head of the pump using the energy equation from pt. A to pt. C. The fluid is water with a kinematic viscosity of 1.02 x 10-6 m³/s. El. 20 m Water B 180-mm dia. pipe 200-m long pipe 300-m long pipe 120-mm dia. pipe El. 10 m El. 30 m

Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P5-14. a. Which sequence of operations, (l?2) or (2?1), will yield the greatest recovery of material A? b. What will be the purity of material A using that sequence? c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stesed equation?

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?
