6. Conversion of Pressure to Head of a Fluid Given the pressure of 1 standard atnm as to 1.325 kN/m2. Do as follows. (a) Convert this pressure to head in m water at 4°C, the density of water at 4°C is 1.000 g/cm*, a density of 1.000 g/cm equals 1000 kg/m

Answer 1

Solution:

Pressure due to the vertical column of a fluid of height H, density $\rho$ is given by

P = $\rho$gH

If pressure = 1.325 kN/m², is due to a column of water, then

$\rho$gH = 1.325 kN/m²

(1000 kg/m²) (9.81 m/S²)H = 1.325 x 10³ N/m²

1.325x10 (1000kgm-3) (9.81ms-2)

H = 0.135066 m water

H = 135.066 mm water
