Which option explains why an environmental group is interested in the project in the following scenario? An environmental group is partnering with a team of chemical engineers to develop oil for machines that will increase their efficiency while decreasing the usage of fuel.

Decreasing fuel usage leads to a reduction in carbon emissions, which is a significant "green" issue.

Environmentalists like to see increased power in machines to cut down on the amount of waste production.

Decreased fuel costs will allow the group to have more money to focus on their issues.

Sustainable machines are the primary goal of environmentalists.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
