PRESSURE

Study the schematic below carefully and answer the questions below:

Solve the following problem $-$ show steps $($The building is $7$ floors high$)$

Determine the pressure at the roof of the building

Determine Pressure at point B

Determine Pressure at the bottom of the water tower $($Street level $100)$

Pressure in the tower was tested to be $25$ PSI $--$ At what elevation was the testing point? Give answer in terms of $1)$ feet above ground and $2)$ elevation

Answer:

A water heater was installed in a bathroom in the $3^{rd}$ floor apartment. Test was done about $7$ feet above the floor

$A_1{V}_1=A_2{V}_2$

A rectangular pipe with a cross section of $1ft.2ft.$ is flowing full at a $4$ CFS velocity of $2$ feet per second $($FPS$).$ What is the flow in CFS$?$ in GPM$?(1800$ gpm$)$

A $24$ inch diameter pipe is flowing full at $2$ FPS$.$ What is its flow in CFS$?$

$(6\mathrm{.}28$ CFS$)$

What is the vel. in FPS of a $48$ inch dia. pipe flowing full at $12,500$ GPM$?$

$(2\mathrm{.}22$ FPS$)$

Compute the flow in GPM in a $42"$ dia. pipe flowing at a vel. of $3\mathrm{.}5$ FPS$?$

$(15,100gpm)$
