Develop an interactive computer program that determines either the system's coefficient of performance or its cooling capacity in tons (allow the user to choose which) of a vaporcompression cycle air conditioner, refrigerator, or heat pump (again allow the used to choose which).
Prompt the user for all necessary information (in proper units) and produce a screen diagram of the system with all the variables and the unknowns shown.
A bicycle tire is filled with air to a pressure of 81.0 psi at a temperature of 19°C. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58°C. The volume of the tire increases by 2.0%. What is the new pressure in the ..
