A 6-cm-diameter horizontal stationary water jet having a velocity of 40 m/s strikes a vertical plate. Determine the force needed to hold the plate if: (a) It is stationary (b) It moves away from the jet at 20 m/s (c) It moves into the jet at 20 m/s (Answer: (a) 4524 N (b) 1131 N (c) 10,180 N)

3. The mass C is connected by two wires to the vertical shaft AB. Rotation of the shaft causes the mass to travel in the horizontal circle shown. Calculate the speed vo of the mass that would result in equal tensions in the wires. 25° 0.6 m 50⁰ VO

A water tank is in the shape of frustum of a cone with height 6 m. and upper and lower radii 4 m. and 2 m., respectively. If water pours into the tank at a rate of 20 m3/min, how fast is the water level rising when the water is 3m from the top? a. 1.698 cm/s b. 1.019 cm/s c. 1.179 cm/s d. 0.707 cm/s

1.90m/s is wrong. Please show me the correct answer.

A 2-in diameter water jet with a velocity of 100 fps shown below impinges on a single vane moving in the same direction (see U1 =60 fps). If the angle B2 is equal to 150 degrees and friction loss over the vane makes V2 = 0.9V1, compute the reaction forces in both the x and y direction. the vane (magnitude and direction). V = 100 Uj = 60 %3D Bz = 150° %3D

Q4: A tank of water empties by gravity through a horizontal pipe into another tank in figure (1) .There is a sudden enlargement in the pipe as shown.At a certain time the difference in levels is 3m.Each pipe is 5m long and has a friction coefficient Cf-0.007 The inlet loss constant is K=0.5 and bore diameter in point A 20mm ,and bore diameter in point B 60mm.Calculate this point. the volume flow rate at Calculate the volume flow rate at this point. (1) 20 mm bore diameter 3 m 60 mm bore diameter (2)
