Estimate the annual operating cost of providing refrigeration to a condenser with duty 1.2 MW operating at -5 ºC. The refrigeration cycle rejects heat to cooling water that is available at 40 ºC, and has an efficiency of 80% of the Carnot cycle efficiency. The plant operates for 8000 hours per year and electricity costs $0.06/kWh.
How long must the tube be made if the outlet oil temperature is 60 C? The Nusselt number for oil side is 5.56. F. water side.
Propose a model which will show how temperature in the tank changes with time. State assumption used. Solve this model to obtain T(t) given that T(t=200s) = 50°C.
You have two identical containers at a fixed temperature. In one you have water vapor (H2O) and in the other you have carbon dioxide (CO2). In the high-temperature, classical limit for vibrations and rotations, meaning that (rotation angle
