The heat engine receives 17,000 kJ/h from the high temperature reservoir, and delivers half of its power output to drive a Carnot heat pump. The Carnot heat pump removes heat from the cold surroundings at 0oC and transfers it to a house which is maintained at 24oC. If the house is losing heat at a rate of 80,000 kJ/h, determine the temperature TH of the heat engine reservoir. What was the significance of the Immigration and Nationality Act of 1965?A.

The design specifications call for an average of 60 pounds per square inch of pressure in each can, with an upper specification limit of 65 psi and a lower specification limit of 55 psi. A sample is taken from production and it is found that the cans average 61 psi, with a standard deviation of 2 psi. Also, the process will stop if the process starts making cans that are more than three standard deviations above or below the average. What is the capability index of this production process?
