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

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

What is the volume of this rectangular

Basile [38]

<h3>Given:</h3>

l= 5 m
b= 4 m
h= 3 m

<h3>Note that:</h3>

l= length
b= breadth
h= height

<h3>To find:</h3>

The volume of the given rectangular pyramid.

<h3>Solution:</h3>

$\large\boxed{Formula:V=\frac{1}{3}lbh}$

First, multiply the length (5), breadth (4) and height (3).

$5×4×3$

$= 60 \: cm$

Now, divide 60 by 3.

$\frac{60}{3}$

$\large\boxed{V= 20 \: {m}^{3}}$

<u>Therefore, the volume of the given rectangular pyramid is 20 cubic meters.</u>

I bought a car of 650,000 and<br>sold it for 520,000. Find the<br>lost Percent ?<br>

Tom [10]

Answer:

20% decrease in value.

Step-by-step explanation:

Do 650,000 divided by 100 to find what 1% of the original price is:

650,000 divided by 100 = 6,500

To find what percentage of the original price 520,000 is, we divide it by 1% of the original cost (6,500):

520,000 divided by 6,500 = 80 (percent)

So if 520,000 is 80% of 650,000 the car has decreased in value by 20%.
