An oil pump operating at steady state delivers oil at a rate of 10 lb/s through a 1-in.-diameter exit pipe. The oil, which can be modeled as incompressible, has a density of 70 lb/ft3 and experiences a pressure rise from inlet to exit of 40 lb/in2. There is no significant elevation difference between inlet and exit, and the inlet kinetic energy is negligible. Heat transfer between the pump and its surroundings is negligible, and there is no significant change in temperature as the oil passes through the pump. Determine the velocity of the oil at the exit of the pump, in ft/s, and the power required for the pump, in hp.

An oil pump operating at steady state delivers oil at a rate of 10 lb/s through a 1-in.-diameter exit pipe. The oil, which can be modeled
as incompressible, has a density of 70 lb/ft3 and experiences a pressure rise from inlet to exit of 40 lb/in2. There is no significant
elevation difference between inlet and exit, and the inlet kinetic energy is negligible. Heat transfer between the pump and its
surroundings is negligible, and there is no significant change in temperature as the oil passes through the pump.
Determine the velocity of the oil at the exit of the pump, in ft/s, and the power required for the pump, in hp.

Science that deals with the amount of energy transferred from one equilibrium state to another equilibrium state.

Thermodynamics of the Otto cycle (gasoline engine) A gasoline engine is an internal combustion engine, typically consisting of one or more piston-cylinder assemblies. The operation of a gasoline engine is approximated by the Otto cycle, composed of the following processes: Point 1: (start of the cycle), the cylinder is at its maximum volume Vmax: A cold mixture of fuel and air is introduced into the cylinder. Process 1 → 2 (compression stroke): The cylinder contracts until the volume of the cylinder reaches Vmin, compressing the fuel-air mixture adiabatically. Work is done by on the system by its surroundings. Process 2 → 3 (): A spark is generated within the cylinder, igniting the fuel-air mixture. The fuel burns very rapidly, such that the volume of the cylinder changes by approximately zero during this step. The combustion of the fuel corresponds to a heat transfer Qin into the system during this constant-volume, or isochoric, process. Process 3 → 4 (power stroke): The cylinder…
