The water of a 14’ × 48’ metal frame pool can drain from the pool through an opening at the side of the pool. the opening is about h = 1.18 m below the water level. the capacity of the pool is v = 3870 gallons, the pool can be drained in t = 12.3 mins. p0 is the pressure of the atmosphere. rho is the density of the water. show answer correct answer 14% part (a) write the bernoulli’s equation of the water at the top of the pool in terms of p0, rho, h. assuming the opening is the origin.

the device is called “ rocket engine”

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
