A pump s =netted to an electric mob The motor is supplied with 1.5 A of current from a 12 VDC some (VDC = direct current wits). The apparatus is run steadily for 45 seconds, and the following measurements are recorded:

• Mass of fluid collected: 800 grams

• Diameter of oat tube: 0.5 inch

• Density of rater 1000 kg/m ³

• Height of fluid exit above reservoir: 38 inches

Find

a. The weight of the fluid collected W = 7.848N

b. Fluid velocity at exit in m/s (meters per second) v = 0.14m/s

c. Flow rate in L/min (1 titer = 0 001 m ³) Q = 1.067 L/min

d. System efficiency (express as a percentage) η = 0.94%
