) One of the major functions of cooling tower is to cool hot but dry gas flow via spray vaporization under a counter-flow mode.

a);List governing mechanisms (e.g., mass, momentum and heat transfer) and major assumptions for problem simplification;

b);Establish a heat transfer model of gas cooling, as well as a hydrodynamics model of droplet transport that is coupled with gas heating and vaporization

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.

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...

Which of the following is an example of homeostasis? a. In hot and dry temperatures, plants will eventually wilt as the amount of water lowers in their cells. b. Water moves down its concentration gradient. c. When the concentration of glucose in the blood is low, glycogen is broken down into glucose. d. A human's body temperature increases while running. e. Uterine contractions trigger the release of a hormone that then triggers stronger uterine contractions.

A hot-air balloon stays aloft because hot air at atmospheric pressure is less dense than cool air at the same pressure. The volume of a balloon is V = 1000.0 m3, and the surrounding air has a temperature T0 which is 10.0 degrees C. The density of air at 10.0 degrees C and atmospheric pressure is p0=1.23 kg m-3. a. What must the temperature T of the air in the balloon be for it to lift a total load of...

The mean water temperature downstream from a power plant cooling tower discharge pipe should be no...

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.

The mean water temperature downstream from a discharge pipe at a power plant cooling tower should...

The mean water temperature downstream from a discharge pipe at a power plant cooling tower should be no more than 100°F. Past studies has shown that the standard deviation of temperature is 2°F. The water temperature was measured on 10 randomly chosen days, and the results are shown below: 96.15 97.81 97.09 95.08 99.46 100.03 99.74 98.85 95.08 98.71 a. State the null hypothesis and alternative hypothesis for the above problem. b. Is there evidence that the water temperature is...

CITIC Tower II: The Real Option It was three o’ clock on a hot afternoon in Hong Kong in mid-2000. Larry Yung, Chairman of Citic Pacific Limited (“CPL”), was having a board meeting with his property development rd team. From his window on the 33 floor of Citic Tower, he could see the impressive Victoria Harbour and an undeveloped prime waterfront site. This piece of reclaimed land had been purchased by a company six months earlier at a public auction....

A sample of gas with a thermometer immersed in the gas is held over a hot plate. A student is asked to give a step-by-step account of what makes our observation of the temperature of the gas increase. His response includes the following steps. (a) The molecules speed up. (b) Then the molecules collide with one another more often. (c) Internal friction makes the collisions inelastic. (d) Heat is produced in the collisions. (e) The molecules of the gas transfer...

Hot water was poured into an empty pop can and allowed to cool in surroundings whose temperature is 20 °C. The initial temperature of the water is 92 °C. After 12½ min the water temperature had dropped by 10 deg C. Assume the rate of change of the water temperature is directly proportional to the difference in the temperature between the water and its surroundings. a. What is the value of the proportionality constant? b. What is the temperature of...
