Question

The head produced by a liquid of relative density
1.62 is equal to the pressure of 250 kPa. What is
the head (m) produced by the liquid?​

Answer 1

Given info : The head produced by a liquid of relative density 1.62 is equal to the pressure of 250 kPa.

To find : the head produced by the liquid.

Solution : head produced by liquid due to pressure is given by, h = P/ρg

Where P is pressure, ρ is density of liquid and g is acceleration due to gravity.

Here, P = 250kPa = 2,50,000 Pa

ρ = 1.62 × 10³ kg/m³ [ liquid density = relative density × density of water at 4°C]

g = 9.8 m/s²

So , h = (250000)/(1.62 × 10³ × 9.8)

= (250)/(1.62 × 9.8)

= 15.75 m

Therefore head produced in m by liquid is 15.75m
