a) A natural draft cooling tower is used to cool the condenser of a 100 MW power plant. The water enters the tower at 40 °C at a rate of 80 kg/s. The range value of cooling tower is 15 °C. The water is cooled by air stream and the air entering the tower is at 1.01325 bar, 23°C and 60% relative humidity. The air leaves the tower as saturated at 32°C. According to the given data, using pyschrometric chart and steam table, determine the volumetric flow rate of air flowing into the cooling tower.

b) Describe briefly the definition and function of cooling tower fill material.

This is problem 7-3 from El-Wakil’s Powerplant Technology book -- a natural-draft cooling tower is 450 ft high. Air enters the tower at 14.696 psia, 50°F, and 50 percent relative humidity and leaves in a saturated condition. The pressure drop in the tower is 0.015 psi. Calculate (a) the air exit temperature, in degrees Fahrenheit, and (b) the makeup due to evaporation, in pound mass per pound mass of dry air.

This is problem 7-5 from El-Wakil’s Powerplant Technology book -- an included-draft cooling tower cools 90,000 gallons per minute of water from 84 to 68 degFahrenheit. Air at 29.75 inHg absolute pressure, 70 degFahrenheit dry bulb and 60 degFahrenheit wet bulb, enters the tower and leaves saturated at 80 degFahrenheit. Find (a) the volume flow rate of air, in cubic feet per minute, and (b) the makeup water required, in pound mass per hour.

The cross-section of a nuclear power plant's cooling tower is in the shape of a hyperbola. Suppose the tower has a base diameter of 156 meters and the diameter at its narrowest point, 48 meters above the ground, is 52 meters. If the diameter at the top of the tower is 104 meters, how tall is the tower? The tower is about ___ meters tall.

You have been asked to evaluate the economic implications of various methods for cooling condenser effluents from a 200-MW steamelectric plant. There are two basic types of cooling towers: wet and dry. Furthermore, heat may be removed from condenser water by (1) forcing (mechanically) air through the tower or (2) allowing heat transfer to occur by making use of natural draft. Consequently, there are four basic cooling tower designs that could be considered. Assuming that the cost of capital to...

Newton's Law of Cooling: Boil water in a cup and cool in a room at 32∘C. Assume that Newton's Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. We take the water temperature after 5 minutes and find it to be 83∘C. Establish and solve an Initial Value Problem to express the water temperature as a function of time, graph...

The mean water temperature downstream from a power plant cooling tower discharge pipe should be no more than 97oF. Past experience has indicated that the standard deviation of temperature is 2oF. The water temperature is measured on 4 randomly chosen days, and the average temperature is found to be 94oF. Conduct a hypothesis testing using the 7 steps at a 5% significance level.
