1. What is flow energy? Do fluids at rest possess any flow energy?
2. How do the energies of a flowing fluid and a fluid at rest compare? Name the specific forms of energy associated with each case.
3. A house is maintained at 1 atm and 24°C, and warm air inside a house is forced to leave the house at a rate of 150 m3 /h as a result of outdoor air at 5°C infiltrating into the house through the cracks. Determine the rate of net energy loss of the house due to mass transfer.
