Answer:

60 cm²

Explanation:

Pressure = Force / Surface area

This is a 2 stage problem which requires working out pressure of piston A and then using that pressure from piston A to calculate the surface area of piston B

Firstly work out pressure of Piston A:

Pressure = 200 / 4

Pressure = 50 N/cm²

Then work out the Surface area of piston B :

Since the pressure is transferred the pressure stays the same so :

Surface area = Force / Pressure

Surface area = 3000 / 50

Surface area = 60 cm²

Water at room temperature is discharged from a pipe at a rate of 1000 gallons per minute (gpm). Express this flow rate in cubic
marshall27 [118]

Answer

given,

discharge rate from pipe = 1000 gallons/minutes

now,

flow rate in  cubic meters per second

1 gallon = 0.00378541 m³

1 min = 60 s

Q = 1000\times \dfrac{0.00378541\ m^3}{1\ gallon}\times \dfrac{1\ min}{60\ s}

Q = 0.063 m³/s

flow rate in  liters per minute

1 gallon = 3.78541 L

 Q = 1000\times \dfrac{3.78541\ m^3}{1\ gallon}

 Q = 3785.41 m³/min

flow rate in cubic feet per second

 1 gallon = 0.133681 ft³

 1 min = 60 s

Q = 1000\times \dfrac{0.133681\ ft^3}{1\ gallon}\times \dfrac{1\ min}{60\ s}

Q = 2.23 ft³/s
