Oil at 150 c flows slowly through a long, thin-walled pipe of 30-mm inner diameter. the pipe is suspended in a room for which the air temperature is 20 c and the convection coefficient at the outer tube surface is 11 w/m2 k. estimate the heat loss per unit length of tube.

8 meters above the spring

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.
