Attach adapter and 1/2" PVC pipe to hose.€L˜ 2 ÿ b. Hold pipe horizontal and turn on water.€L˜ 5 ÿ c. Measrure and record the x and y distances.€L˜ n ÿ d. Substitute values into the formula and determine the "theoretical" discharge rate.€L˜ q ÿ e. Using the stop watch, determine the time required to fill the one gallon milk jug.€L˜ H ÿ f. Convert the data into "actual" gallons per minute flow rate.€L˜ C ÿ g. Compare the theoretical results with the actual results.€L˜ 9 ÿ h. Repeat the experiment using the 3/4" PVC pipe.€L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ 6ÿUNIT 15 - Using Formulas to Solve Problemsÿ€L˜ 2ÿLAB ACTIVITY B -Calculating Water Flowÿ€L˜ €L˜ €L˜ ; ÿName____________________________ Date__________€L˜ * ÿ ____________________________€L˜ * ÿ ____________________________€L˜ €L˜ €L˜ €L˜  ÿ1/2" PVC Pipe ÿ€L˜ €L˜ €L˜ €L˜ €L˜ €L˜  ÿTheoretical:€L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ @ ÿActual: Time (in seconds) to fill one gallon jug.________€L˜ €L˜  ÿ1 gallon 60 seconds€L˜ H ÿ------- ---------- = ____________ gallons per minute (gpm)€L˜  ÿ_____sec 1 min. €L˜ €L˜  ÿ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜  ÿ3/4" PVC Pipe ÿ€L˜ €L˜ €L˜ €L˜ €L˜ €L˜  ÿTheoretical:€L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ €L˜ @ ÿActual: Time (in seconds) to fill one gallon jug.________€L˜ €L˜  ÿ1 gallon 60 seconds€L˜ H ÿ------- ---------- = ____________ gallons per minute (gpm)€L˜  ÿ_____sec 1 min. €L˜ €L˜ €L˜ €L˜ €L˜  ÿ
