Water flows in a horizontal pipe of d1=100 mm with a velocity wt=1m/s and pressure p1=90...

Water flows in a horizontal pipe of d1=100 mm with a velocity wt=1m/s and pressure p1=90 kPa. It enters a pipe reduction to a diameter d2=50 mm. Pressure after the pipe reduction drops to p2=80 kPa while temperature is unchanged. Find entropy generation rate in the zone of the pipe reduction. Assume that the surroundings is at Ts=20?C and pressure is ps=80kPa and the steady state is considered. What will be the exit pressure after the pipe reduction if the...

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm in diameter. A pump maintains a gauge pressure of 742 Pa at a large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length 9 m and diameter 5.0 cm, what gauge pressure must the pump provide to give the same volume flow rate...

Steam enters a horizontal 15-cm-diameter pipe as a saturated vapor at 5 bar with a velocity of 10 m/s and exits at 4.5 bar with a quality of 95%. Heat transfer from the pipe to the surroundings at 300K takes place at an average outer surface temperature of 400 K. For operation at steady state, determine (a) the velocity at the exit, in m/s. (b) the rate of heat transfer from the pipe, in kW. (c) the rate of entropy...

A mass of 8 kg stretches a spring 16 cm. The mass is acted on by an external force of 7sin⁡(t/4)N and moves in a medium that imparts a viscous force of 3 N when the speed of the mass is 6 cm/s.If the mass is set in motion from its equilibrium position with an initial velocity of 4 cm/s, determine the position u of the mass at any time t. Use 9.8 m/s^2 as the acceleration due to gravity....
