Question

Estimate the pressure needed to raise a column of water to the same height as a 42-m-tall pine tree.

Answer 1

The solution for this problem is:P = rho g h rho is density = 1000 kg/m^3 which is the density of water g = acceleration due to gravity force = 9.81 m/s^2h = height
plugging in our values…
P = 1000 kg/m^3 * 9.81 m/ s ^2 * 42 m P = 1000 kg / m^3 * 412.02P = 412,020 or 4.12 x 10^5 N/m^2
