Find the acceleration of an open cylinder with 5 m diameter and holding - 6 m of water if the force acting on the sides is 90 kN.

None

A man is standing on a board on a frozen lake where there is no friction between the board and the ice surface. Tha man's mass is 2 m and the boaf's mass is 4 m. The board has length L. He walks from 1/5 Lfrom the left end of the board to 1/5 L from the right end of the board. How far and in which direction does the board move during this process?

If a liquid enters a pipe of diameter d with a velocity, v. what will irs velocity at the exit be if the diameter reduces to 0.5d?

The water jet in figure, moving at 15 m/s, is split so that one-third of the water moves towardA. Calculate the magnitude and direction of the force on the stationary splitter.

An elevator is accelerated upward at 2 ft/s², if the elevator weighs 500 lbs, what is the tension in the supporting cables? Correct answer is 531 lbs.

In a machine a Newtonian fluid is filled in the clearance between a shaft and a concentric sleeve. The sleeve attains a speed of 50 cm/s, when a force of 40 N is applied to the sleeve parallel to the shaft. What is the speed if a force of 200 N is there?

It is a 20 mm Diameter pipe, its length is 100 mm. The Water is entering into it, at a velocity of 0.0005 m/s. You need to Find the Velocity variation in the Pipe.

Consider a column of water as it falls from a faucet. The opening in the faucet has radius ro and the water comes out with initial velocity vo. Define y to be the distance below the faucet. As the water falls (y increases), it accelerates due to gravity and the stream narrows. a) Assuming streamline flow, find an expression for the velocity of the water for any distance below the faucet. b) The stream obeys the continuity equation. Use this to determine the radius of the stream as a function of y. c) At what distance ₁/2 will the radius of the stream be half its original radius? At what distance Y1/3 will it be a third? d) Compare 1/2 and Y1/3 for v0 = = 1 m/s and v0 = 0.1 m/s (use g = 10 m/s²).
