This 30º vertical bend in a pipe with a 60 cm diameter carries water (r= 1000 kg/m3) at a rate of 1 m3/s. If the pressure p1is 70 kPa at the lower end of the bend, where the elevation is 30 m, and p2is 60 kPa at the upper end, where the elevation is 31 m, what will be the vertical component of force that must be exerted bythe anchor on the bend to hold it in position? The bend itself weights 1400 N, and the length Lis 1.2 m.

explanation:

newton's third law, for every action there is an equal and opposite reaction.

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.
