Solution:
Given:
height of geyser, h = 50 m
speed of water at ground can be given by third eqn of motion with v = 0 m/s:
putting v = 0 m/s in the above eqn, we get:
u = (1)
Now, pressure is given by:
(2)
where,
= density of water = 1000 kg/
g = 9.8 m/
Using eqn (1) and (2):
⇒
=
= 490000 Pa
= 101325 Pa
For absolute pressure, p:
p = +
p = 490000 - 101325
p = 388675 Pa
Therefore, pressure in hot springs for the water to attain the height of 50m is 388675 Pa
