The pressure pump on the second floor of a residential building is connected directly to the outdoor piping network, which can provide a pressure of 0.28 Mpa. The static water pressure required to deliver water to the most unfavorable point in the distribution system is 0.54 Mpa; the total head loss in the piping system is 0.08 Mpa (including a head loss of 0.01 Mpa due to the water meter). The outlet head required at the most unfavorable point in the distribution system is 0.05 Mpa. The head of the water pump is calculated to be ( ) Mpa. Answer: 0.39
(0.54+0.05+0.08)-0.28=0.39Mpa
(0.54+0.05+0.08)-0.28=0.39Mpa
