Unformatted text preview: 3 . 1. Transform the energy used by the town into J. 2. What is the power this town requires to function? 3. How much power can be turned into electricity using this type of wind turbine? 4. How many turbines are necessary to power this town (give an integer number)? Problem # 2 (continued) The turbine area is 6,000m 2 . Problem # 3 Water flows through a pipe with area 2m 2 with a velocity given below. The pipe is connected to another cylindrical pipe with a 20 cm diameter. We suppose the water density is constant at 1,000kg/m 3 . 1. What is the crosssectional area of the smaller pipe? 2. What is mass flow rate of water in the big pipe? 3. What is the volumetric flow rate of water in the big pipe? 4. Using flow rate conservation, find the water velocity in the small pipe. Problem # 3 (continued) The water flows at 3m/s....
