Pressure within the body is an enclosed system and can be calculated by the formula as follows,


Pressure= hρgh\rho g

where h= height of fluid column to be pumped

ρ=\rho = the density of fluid

g=g= the gravitational acceleration assumed as 10 m/s2m/s^2 (N/KgN/Kg )

Pressure = 0.33×1.1×103×100.33 \times 1.1 \times 10^3 \times 10


P= 36330 N/m2N/m^2
