Water enters a 13-cm-diameter pipe steadily with a uniform velocity of 2 m/s and exits with the turbulent flow velocity distribution given by u = umax(1 − rr)1/7 . if the pressure drop along the pipe is 10 kpa, determine the viscous force exerted in the pipe by the water flow. take the density of water to be 1000 kg/m3. the average velocity is equal to 0.816 times the max velocity. the viscous force exerted in the pipe by the water flow is 50

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
