A computerized design facility has a first cost of $750K. The annual O&M is $100K. The salvage value in year 40 is $5K. Computer monitor replacement will cost $250K every 8 years, and other hardware and software will need replacement every 4 years for $300K. If i = 12%, find the EAC for the 40-year horizon.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
