For each problem, sketch the appropriate process diagram on a T-v, P-v, or P-h diagram

4.60 : Steam exiting the turbine of a power plant passes through the insulated shell-and-tube heat exchanger condenser. The mass flow rate of the steam is 145 kg/s, and the steam enters the heat exchanger as a saturated mixture with a quality of 0.95 at 20 kPa. The steam exits the condenser as a saturated liquid at 20 kPa. Liquid cooling water is used to condense the steam. The cooling water enters the condenser at 10 degrees celsius. (a) Determine the exit temperature of the liquid cooling water if the mass flow rate is 4000 kg/s. (b) Using your heat exchanger model, plot the cooling water mass flow rate and volumetric flow rate (entering the condenser) for exit temperatures ranging from 15 degrees celsius to 55 degrees celsius. (c) if the exit temperature of the cooling water is regulated such that it must be no greater than 40 degrees celsius, and if the cooling water flow rate through the condenser can be adjusted in a range from 500 kg/s to 2000 kg/s, what is the range of maximum possible flow rates of steam through the condenser?

For each problem, sketch the appropriate process diagram on a T-v, P-v or P-h diagram 1) Oil enters the outer tube of an insulated concentric tube heat exchanger at a temperature of 500k, and exits at a temperature of 400k. The mass flow rate of the oil is 5 kg/s, and the oil has a specific heat of Cp=1.91 kJ/kg*K. Saturated liquid water at 100 degrees celsius enters the inner tube, and exits at 100 degrees celsius with a quality...

Three players toss coins simultaneously. For each player, P (H) = p, P (T) = q. If the result is 2H and 1T or the result is 2T and 1H, then the player that is different from the other two is called the odd man out and the game is over. If the result is 3H or 3T, then the players toss again until they get an odd man out. Find the probability that the game lasts at least 6...
