Question

Closed Book (There are problems on the back as well!) 1. (8 pts) In the measurement of flow rate of water through the Bernoulli's Theorem Apparatus, a volume of 850 mL water was collected over 50.26 s. What was the flow rate? What was the velocity in the section of the pipe where it has an inner diameter of 25.0 mm? Give correct unit in your answer. 2. (4 pts) There were four different target deflectors used in the impact of jet experiment. Which one was subjected to the greatest impact force? (Circle only one correct answer) a) flat deflector b) conical deflector c) semi-spherical deflector d) sloped deflector 3. (4 pts) There were four different target deflectors used in the impact of jet experiment. Which one was subjected to the smallest impact force? (Circle only one correct answer) a) flat deflector b) conical deflector c) semi-spherical deflector d) sloped deflector 4. (5 pts) As illustrated in the sketch, to which of the following is the reading (h) in the manometer equal? (Circle only one correct answer) a) Head lose in the pipe b) Pressure head in the pipe c) Total head in the pipe d) Velocity head in the pipe (Over)

0 Flow Rate Q = V/t there V= 850 mL = 0.00085 m² te 50.265 so P=10.00085)/50.26) 1043m3/ 19 = 1.69x165 mols d = 25x163m velocity vo & A= ara V= 1.68x10.5 A ( 25x103)2 = 10.034 m/s 1
