gpm = 29.7 \times  {d}^{2}  \times  \sqrt{np}
this formula is used to determine gpm (gallons per minute) of flow with a known hose diameter (d) and nozzle pressure (np). The constant (29.7) is consistent when figuring flow with in gallons with a know pressure expressed in psi (pounds per square inch).

Scenario example: a firefighter is using a handline to fight fire with an 1 3/4 inch line with a nozzle pressure of 100 psi. How much water is the firefighter flowing when fighting fire?

gpm = 29.7 \times  {1.75}^{2}  \times  \sqrt{100}

Alex_Xolod [135]

Answer:

hello :

90 = 15×6

90 = 3² ×2×5

75= 5^3

common multiple of 90 and 75 is : 3²×2×5²  = 450

90 and 75  both smaller than 100.
