How do engineers self-regulate their own profession when it comes to liability? 1) They make everyone aware of environmental concerns and product liability causes and laws.

2)They prosecute any engineer who doesn’t maintain professional affiliation and provide quality design solutions.

3) They use a code of ethics to provide guidelines for protecting people and the environment and for producing quality solutions to design problems.

4) They use legal means to fine everyone who breaks the law and doesn’t protect the environment.

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.
