Chapter 20, Problem 8P

2. Consider the system described in the news: at night, when there is energy left, water is pumped from a large lake to a reservoir at 80 m above the lake level. During the day, this water is used to generate energy in a turbine located 80 m below the elevated reservoir. Considering that the water flow is always 5000 liters/s (both at the inlet of the reservoir and at the outlet) and that the pump and turbine efficiencies are 70%, what is the power (in kW) required by the pump and the power (in kW) recovered in the turbine. Data: The pipe diameter is always the same along the system (d = 0.5 m); g = 10 m/s2; γ = 9810 N/m3. Matter transport phenomena; Please make it typeable as handwriting interferes with understanding

Determine the amount of SO2 released from the combustion of 1500 gallons of waste oil (135,000 BTU/gal) with 1.6 wt % S. The oil has a specific gravity of 0.86. How much reduction would this need to meet NSPS for a 125 MW electric utility steam generation source (35% efficiency)?
