A steady-flow device requires ____ to be zero.Question 8Select one:a.net heat transfer to/from the systemb.work done on/by the systemc.change in enthalpy from inlet to outlet streamd.change in pressure from inlet to outlet streame.change in mass flow rate from inlet to outlet stream

n this course, we commonly assume which of the following for flow devices like pumps, heat exchanges, turbines and compressors?1 pointSteady FlowSteady StateSteady State and Steady FlowSteady State, Steady Flow, Constant Temperature

1.Question 1What causes heat transfer?1 pointA difference in mass flowA difference in temperatureWork transferA difference in specific volume

State the Steady Flow Energy Equation and state what form of energy each termrepresents.

Identify the energy transfer in the completed flow diagram and explain why it is not an energy transformation.

A steady-state, steady flow thermodynamic system receives 100 lbm/min of a fluid at 30 psia and 200F and discharges it from a point 80 ft above the entrance section at 150 psia and 600F. The fluid enters with a velocity of 7,200 fpm and leaves with a velocity of 2,400 fpm. During this process, there are supplied 25,000 Btu/hr of heat from an external source, and the increase in enthalpy is 2.0 Btu/lb. Determine the work done in horsepower.
