$gpm = 29.7 \times {d}^{2} \times \sqrt{np}$
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?

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

Create the Subset and Proper Subset of the set A= {1,2,3,4}. Upload your work.

The subset of A is B = {1, 2} and the proper subset of A is C = {1,2,3,4}

<h3>How to create the Subset and Proper Subset of the set?</h3>

The set is given as:

A = {1,2,3,4}

Subsets of a set are sets that can be found in another set

An instance of this is

B = {1, 2}

Because all the elements of set B are in set A

Proper subsets of a set are sets that contain the exact elements found in another set
