A steam power plant with boiler use coal fuel with net heat 4000 kcal/kg and boiler efficiency 90%. If steam utrbine from the power plsnt generate power output 100 MW, at condition vapor enter at 10 MPa, 520^oC and condensate to saturated liquid at 0.08 bar. If the isentropic efficiency turbine and pump is 90%, then

a) Calculate coal required (ton/hour)

b) Calculate netto efficiency of the power plant

c) Calculate Net Plant Heat Rate (kCal/kWh)

A cylindrical specimen of aluminum having a diameter of 0.75 inches and a length of 8 inches is deformed elastically in tension with a force of 11,000 lb. Assume the following properties: Modulus of Elasticity: 10 Mpsi; Yield Strength: 40 kpsi; Tensile Strenght: 50 kpsi; Percent Elongation: 17; Poisson's Ratio: .33 Determine the following: (a) The amount by which this specimen will elongate in the direction of the applied stress (b) The change in diameter of the specimen. Will the diameter increase or decrease?
