Explain why the following scenario fails to meet the definition of an effective evaluation of a green energy source. Situation: A green community is concerned about possible greenhouse gas emissions. Rather than use biomass, it decides to build a concentrating solar power system, but it needs to clear 100 acres of hardwood forest to do so.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
