1. The problem statement, all variables and given/known dataWhat gauge pressure in the water mains is necessary if a firehose is to spray water to a height of 20 ?

2. Relevant equations

Pressure = density * gravity * chanfe of height

3. The attempt at a solution

density of the water is 100 kg/m^3

so will the solution be:

100 (kg.^3) * 9.8 (m/s^2)* 20m

=19600 pa????
