A pipe takes water from a reservoir where the temperature is 12 °C to a hydro-electric plant 600 m below. At the 1.2 m diameter inlet to the powerhouse the gaugepressure of the water is 5.5 MPa and its mean velocity 2 m: s'. If its temperature there is13.8 °C, at what rate has heat passed into the pipe as a result of hot sunshine? (Note: Thechange of atmospheric pressure over 600 m must be accounted for: mean atmosphericdensity = 1.225 kg m³. Specific heat capacity of water = 4.187 kJ · kg ·K-1.)S

Q3// A 180 cm-diameter tank is 4 points initially filled with water 220 cm above the center of a sharp edged 15 cm diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere. Neglecting the effect of the kinetic energy correction factor, calculate (a) the initial velocity from the tank and (b) the time required to empty the tank. Does the loss coefficient of the orifice cause a significant increase in the draining time of the tank?
