1.Water flows in a rectangular open channel at a critical velocity of 5 m/s. What is teh critical depth and specific energy? Plot a graph showing the discarge per unit width per unit width q for various depths if the specific energy remains constant at this value. What will be the depth when the discharge is 1/3 of the discharge at critical depth ?
2.A 35 percent-efficient coal-fired power plant with effective height of 100 m emits SO2 at a rate of 0.6 lb/10^6 Btu into the plant. If winds are assumed to be 4 m/s at the stack height and just over 3 m/s at 10 m, how large could the plant be (MW) without having the ground level SO2 exceed 365 micrograms/m^3?
