This is from Chapter 10 of Sustainable Energy second edition by Richard Dunlap Two locations have the same average wind velocity. Location A has a constant wind velocity of 10 m/s, while Location B has a wind velocity of 5 m/s for 12 hours per day and a wind velocity of 15 m/s for 12 hours per day. Compare the total energy produced per day for identical wind turbines at the two locations. The energy is given by the formula E = 0.5*(air density)*(efficiency)*velocity^3*(Turbine area)*time. Keep the answer in terms of (efficiency)*(Area). **Also is v average velocity or regular, non-average velocity?***

After graduation, you work for a pump manufacturing company. One of your company’s best-selling products is a water pump, which we shall call pump A. Its impeller diameter is DA = 6.0 cm, and its performance data when operating at n. A = 1725 rpm (?A = 180.6 rad/s) are shown in Table.The marketing research department is recommending that the company design a new product, namely, a larger pump (which we shall call pump B) that will be used to pump liquid refrigerant R-134a at room temperature. The pump is to be designed such that its best efficiency point occurs as close as possible to a volume flow rate of V. B = 2400 cm3 /s and at a net head of HB = 450 cm (of R-134a). The chief engineer (your boss) tells you to perform some preliminary analyses using pump scaling laws to determine if a geometrically scaled-up pump could be designed and built to meet the given requirements. (a) Plot the performance curves of pump A in both dimensional and dimensionless form, and identify the best…
Consider a device similar to that used by Joule to measure the net workbetween two states as depicted in the follow diagram. The mass of the weightconnected by a string to the winding drum is 4 kg. If upon release, the mass falls 0.8meters, by how many joule does the internal energy of the water change? Is the rise inthe internal energy of the water due to work or heat being added to the system?
