`Hydropower Lab Report Instructions: In this lab activity, you will investigate the operation of a simple hydropower system coupled with a wind generator and a gasoline back-up generator. You will test two independent variables: Upper Tank Capacity and Pump Limit . You will run three trials for each test. Use this lab report to collect data and analyze your results. Submit your lab report to your instructor when completed. Title: Hydropower Lab Report Objective(s): See slide 1 of virtual lab for these objectives. List the objectives below. ● investigate the use of hydroelectricity and wind power generation ● examine the effects of hydroelectricity and wind power on the environment ● discuss the advantages and disadvantages of each type of renewable energy resource Variables: The variables are described in detail your virtual lab activity. Be sure to read these descriptions in the virtual lab before completing this section. List your controlled variables, independent variable, and dependent variable of each test of the lab activity. Remember, controlled variables are factors that remain the same throughout the experiment. An independent (test) variable changes so that the experimenter can see the effect on other variables. The dependent (outcome) variable will change in response to the test variable. Test 1 Test 2 Controlled variables initial water level initial gas level Independent variable Upper tank capacity Pump Limit Dependent variable Gas usage rate, water level wind output, consumption Hypothesis: Complete the predictions below. Each test has three dependent variables that may change in reaction to the independent variable, but you are only required to predict the change in the gas usage rate.
Prediction 1: If we increase the upper tank capacity of the water, the gas usage rate will decrease. Prediction 2: If we increase the pump limit, the gas usage rate will increase. Procedure: Access the virtual lab and complete the procedures described. Provide a brief summary of the steps you followed during the experimental procedure. Materials: Hydropower Virtual Lab Summary of Steps: I looked at the Slide for the corresponding Table and marked down the values for eacof the 4 different outputs (Gas usage, water level, wind output, consumption). I then took the average of all of these and marked it below in the table. Data: Table 1: Upper Tank Capacity and Gas Usage *ALL VALUES ARE APPROXIMATES AND UNITS ARE kWh Upper Tank Capacity Gas Usage Water Level Wind Output Consumption Trial 1 6 kWh 9 39 25.5 27.5 Trial 2 8 kWh 7.5 52 25.5 27.25 Trial 3 12 kWh 6.75 64.5 25.5 27.5 Table 2: Pump Limit and Gas Usage Pump Limit Gas Usage Water Level Wind Output Consumption Trial 1 2 kWh 8 51 25.5 27.75 Trial 2 1 kWh 7.5 47.5 25.5 27 Trial 3 0 kWh 11.25 17.5 25.5 27.5
