Chapter 8, Problem 8.82(choose chapter or problem)
As shown in Fig. P8.82, a standard household watermeter is incorporated into a lawn irrigation system to measurethe volume of water applied to the lawn. Note that these metersmeasure volume, not volume flowrate. (See Video V8.16.) With anupstream pressure of p1 = 50 psi the meter registered that 120 ft3of water was delivered to the lawn during an on cycle. Estimatethe upstream pressure, p1, needed if it is desired to have 150 ft3delivered during an on cycle. List any assumptions needed toarrive at your answer.
