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 of 0.20. Determine the mass flow rate of the water.

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...

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...
