horizontal cylindrical tank filled with liquid but we dont know it height of liquid so how we find out and how we calculate volm of liquid only we know about length or diameter of cylinder

An open cylindrical tank 4 ft in diameter and 6 ft deep is filled with water and rotated about its axis at 60 rpm. How much liquid is spilled, and how deep is the water at the axis? Ans. 15.3 ft , 3.55 ft , give the solution.

Assume 2 kg of hydrogen (Item B 28) are initially at 40 atm, 100 K. (a) If the hydrogen changes pressure to 1 atm without a change of temperature, find the changes of enthalpy and entropy. (b) If the hydrogen changes temperature to 35 K with no change of entropy, find the change of pressure and enthalpy.

In a single slider crank mechanism, the length of crank and connecting rod are

125 mm and 500 mm respectively. The crank speed is 600 RPM Clockwise.

When the crank has turned 45° from the inner dead centre position, determine

the velocity of the slider

Determine the output of the LTI system for the input x[n and impulse response of the

system h[n]

x[n] = {2,7,1,5)

h[n] = {6,2,5,9,1)

(a) {12, 46, 30,85,78,42,47,5

(b) {12,46,30,85,80, 40,47,5}

(c) {12,46,30,85, 78,47,42,5}

(d) {12,46, 30,85,80, 41, 46,5}​

a gear train consisting of bevel gears, spur gears and a worm and worm

gear. The bevel pinion is mounted on a shaft driven by a V-belt on pulley. If pulley 2 rotates at

1200 r.p.m. in the direction shown, find the speed and direction of rotation of gear 9.

An open cylindrical tank 4 ft in diameter and 6 ft deep is filled with water and rotated about its axis at 60 rpm. How much liquid is spilled, and how deep is the water at the axis?

a compound gear train in which, wheel A is fixed to the driving shaft, B-C are

compounded , D is idle, and E is fixed on the driven shaft. If gear A rotates at 1000 r.p.m find

the speed and direction of E. driven shaft.

9.) The pressure head at A in pump A B is 120 ft when the energy change in the system (see Fig. 9-30) head through valve Z is 10 ft. Find all the flows and the elevation of reservoir Sketch the hydraulic grade lines.

10.) Solve the pipe network shown in the figure. The 12 in and 16in are of new cast iron, while the 18 and 24 in are of average concrete. Assume n=2.0 and use the values of f from figure 8.11 for complete turbulence. If the pressure at h is 80 psi, find the pressure at f.

5.) An old pipe, 600 mm I.D. and 1219m long, carries medium fuel oil at 30°C from A to B. The pressures at A and B are 393 kPa and 138 kPa respectively, and point B is 18.3 m above point A. Calculate the flow, using ∊ = 0.00049 m.

6.) A commercial solvent at 20°C flows from tank A to tank B through 152 m of new 150-mm asphalt-dipped cast iron pipe. The difference in elevation of the liquid levels is 7.0 m. The pipe projects into tank A, and two bends in the line cause a loss of 2 velocity heads. What flow will occur? Use ∊ = 0.00014 m.

7.) A 12-in-diameter new cast iron pipe is 1.0 mile long. Determine the discharge capacity of this pipe if the head loss is 24.5 ft using: a.) Hazen-Williams formula. b.) Manning formula.
