At an ocean-side nuclear power plant, seawater is used as part of the cooling system. This raises the temperature of the water that is discharged back into the ocean. The amount that the water temperature is raised has a uniform distribution over the interval from 10 to 25�C. (a) What is the probability that the temperature increase will be (1) less than 20 degrees C? (2) between 20 and 22C?(b) Suppose that a temperature increase of more than 18 degrees...

A centrifugal pump test yields the following data: Pump Head Flow (m)(L/min) 30 25 20 40 The pump curve can be approximated by a parabola. This pump draws water from a large reservoir. The discharge of the pump feeds 150 m of 1.5 cm inside diameter pipe and then 225 m of 3 cm inside diameter pipe.. The two pipes both have a roughness of 0.5 mm The 3 cm pipe discharges to atmosphere a distance 40 m below the...

A nuclear power plant generates 3000 MW of heat energy from nuclear reactions in the reactor's core. This energy is used to boil water and produce high-pressure steam at 320 ∘C. The steam spins a turbine, which produces 1000 MW of electric power, then the steam is condensed and the water is cooled to 25∘C before starting the cycle again. Part A: What is the maximum possible thermal efficiency of the power plant? Part B: Cooling water from a river...

An evaporative cooling tower removes 1 x 106 Btu/hr of heat from the cooling water from a condenser of a steam power plant. The temperature of the water is reduced from 120 °F to 110 °F. Air enters the cooling tower at 91 °F and 60% relative humidity and air leaves at 100 °F and 82% relative humidity. The quantity of make-up water is:

The water flowing through a 2.0 cm (inside diameter) pipe flows out through three 1.4 cm pipes. (a) If the flow rates in the three smaller pipes are 25, 19, and 12 L/min, what is the flow rate in the 2.0 cm pipe? (b) What is the ratio of the speed of water in the 2.0 cm pipe to that in the pipe carrying 25 L/min?

The water flowing through a 1.9 cm (inside diameter) pipe flows out through three 1.1 cm pipes. (a) If the flow rates in the three smaller pipes are 27, 16, and 12 L/min, what is the flow rate in the 1.9 cm pipe? (b) What is the ratio of the speed of water in the 1.9 cm pipe to that in the pipe carrying 27 L/min?

(b) Figure Q3 shows a design of a plumbing system to be used in a new building. Water at 20°C is free to be pumped from reservoir A to another reservoir B at a higher elevation through two 30 m long pipes connected in parallel on a common elevation level. The difference between the water surface elevations is 10 m. The pipes are made of commercial brass and the diameters of the two pipes are 4 cm and 8 cm....

Consolidated Power, a large electric power utility, has just built a modern nuclear power plant. This plant discharges waste water that is allowed to flow into the Atlantic Ocean. The Environmental Protection Agency (EPA) has ordered that the waste water may not be excessively warm so that thermal pollution of the marine environment near the plant can be avoided. Because of this order, the waste water is allowed to cool in specially constructed ponds and is then released into the...
