Aside from the change in temperature what else is negligible for mechanical energy balance. It is not related to the Bernoulli equation.
Homework Answers
For mechanical energy balance temperature is constant so that density of fluid remain same .
Apart from that correction factor is taken as 1, no change in fluid velocity with time and space so velocity variation with time and space is negligible because we assume constant mass flow rate .

Conservation of mechanical energy A 1.10-kg ucket is tied to a rope of negligible mass. The rope is wrapped around a pole that s mounted horizontally on frictionless bearings. The cylindrical pole has diameter of 0.3 point. Use this information for questions 10, 11, 12, and 13. You must show equations used and all your work that leads to correct answer.
