The average power of a wind turbine is 3 MW. One house consumes an average of 16,000 kW. h per year.
1. Express in joules (j) the average annual energy consumed by this dwelling.

2. Find the number of homes that can be powered by a wind turbine.
Hint: 1 MW = 106 W

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
