Question

a plumbing branch is composed of 68ft if 1 in diameter type l copper pipe, three 90 elbows and a gate valve. the elevation increase in 12ft determine the total pressure drop accorss the plumbing branch if it is carrying water 45 gpm

Answer 1

To determine the total pressure drop across the plumbing branch, we need to consider the pressure losses due to friction and elevation change. The pressure drop due to friction can be calculated using the Darcy-Weisbach equation, while the pressure drop due to elevation change can be calculated using the hydrostatic pressure equation.

Step-by-step explanation:

To determine the total pressure drop across the plumbing branch, we need to consider the pressure losses due to friction and elevation change. The pressure drop due to friction can be calculated using the Darcy-Weisbach equation:

ΔP = ρgL

Where ΔP is the pressure drop, ρ is the density of water, g is the acceleration due to gravity, and L is the length of the pipe. The pressure drop due to elevation change can be calculated using the hydrostatic pressure equation:

ΔP = ρgh

Where h is the elevation increase.
