A trough is 3 meters long, 2 meters wide, and 4 meters deep. The vertical cross-section of the trough parallel to an end is shap
ed like an isoceles triangle (with height 4 meters, and base, on top, of length 2 meters). The trough is full of water (density 1000 kg m 3 1000kgm3 ). Find the amount of work in joules required to empty the trough by pumping the water over the top. (Note: Use g = 9.8 m s 2 g=9.8ms2 as the acceleration due to gravity.)
No its not possible in that yes heat flow is due to temperature different but with time equilibrium in temperature is reached hence there is no temperature difference at both ends at this time
