A house with its own well has a pump in the basement. The pump output pipe has an inner radius of 6.60 mm. A showerhead on the second floor, 7.49 m above the output pipe, has 46 holes, each with radius of 0.393 mm. The shower is on full blast and no other faucet in the house is open. If the water leaves the showerhead with 29.1 m/s, what is the gauge pressure in the output pipe? Answer in kPa. (1) 487.04 (2) 509.57 (3) 899.18 (4) 473.09 (5) 429.25 When discussing the motion of fluid across a height difference, Bernoulli's equation should be used: 5 P(07 - 12) = (P2 - Pi) +pg (12 - y1) (P2 - Pi) - 2 gh Ui - 15 = Panuge - 2 g h
