Chapter 12, Problem 2RQ
  1. 2. When we wish to generate hydroelectric power, we build a dam to back up the water in a river. If the water has a height (H, in units of feet) above the downstream discharge, and we can discharge water through the turbines at a rate (Q, in units of cubic feet per second [cfs]), the maximum power (P, in units of kilowatts) we can expect to generate is:

    P=CHQ

Chapter 12, Problem 2RQ, 2. When we wish to generate hydroelectric power, we build a dam to back up the water in a river. If For a small "run of the river" hydroelectric facility, we have obtained the following data.

  1. a. Using the trendline results, and examining the preceding general equation, determine the value and units of the coefficient C for a height of 20 feet.
  2. b. If the flowrate was 30 cubic feet per second and the height is 3 meters, what would the power output be in units of horsepower?
  3. c. If the flowrate was 20 cubic feet per second and the height is 8 meters, what would the power output be in units of horsepower?

Suppose a hippopotamus on land receives 73 units of heat per minute due to solar radiation and 52 units of heat per minute due to infrared radiation. It emits 39 units of infrared radiation and it loses 66 units heat per minute through evaporation. The hippopotamus gains 45 units of heat per minute through its metabolism. Overall, its heat energy is increasing by 50 units per minute (i.e. its temperature is increasing). Delta Hanimal = SR + IRin - IRout ± Hconv ± Hcond - Hevap + Hmet Based on this information we can conclude that the combination of conduction and convection is the animal, and that its current temperature is than the ambient temperature. Select one: a. cooling; warmer b. warming; warmer c. cooling; cooler d. warming; cooler
Question 1 Consider the hot water heater (geyser) in your house. Classify each case below as an open system, closed system, neither or both. Then provide a simplified energy equation to describe each system, justifying each simplification made. State all assumptions clearly. a) The tank is being filled with cold water b) Hot water is being drawn from the tank c) The tank leaks d) The heater is turned on to heat the water as water enters the geyser e) The tank is full and the heater is turned off
