Water at 940 kPakPa , 25∘C∘C enters a 1-mm-diameter horizontal pipe with a steady velocity of 19 m/sm/s . At the exit the pressure drops to 860 kPakPa due to viscous resistance. Assuming steady-state flow, determine the rate of heat transfer (Q˙Q˙) necessary to maintain a constant specific internal energy (uu).

we are supposed to find the rate of heat transfer

20.3 cm diam 2.44 m 1.22 m Water Air at 105 kPa and 37°C flows upward through a 6-cm-diameter inclined duct at a rate of Q (L/s). The density of air at this temperature and pressure is 1.10 Kg/m³. The duct diameter is then reduced to 4 cm through a reducer. The pressure change across the reducer is measured by a water Air manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.20 m. Determine the differential height between the fluid levels of the two arms of the manometer. Q (L/s) 90

S CE - Oil is transported from A to B along a pipe of constant diameter. The pipe is inclined at 50° to the horizontal and B is at the higher elevation. Considering the flow from A to B, which statement is correct? O The pressure head is decreasing and the velocity head is increasing. O The pressure head is increasing and the velocity head is decreasing. O The pressure head and velocity head are both increasing. O The pressure head is decreasing and the velocity head is constant. O The pressure head and velocity head are both decreasing.
