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.
1.) What size pipe will maintain a shear stress at the wall of 0.624 psf when water flows through 300 ft of pipe causing a lost head of 20.0 ft?
2.) Compute the critical velocity (lower) for a 100-mm pipe carrying water at 27°C.
3.) Water at 20°C flows in a 100-mm-diameter new cast iron pipe with a velocity of 5.0 m/s. Determine the pressure drop in kPa per 100 m of pipe and the power lost (in kilowatts) to friction.
4.) Water at 38°C flows from A to B through 244 m of average 300-mm-I.D. cast iron pipe (∊ = 0.00061 m). Point B is 9.1 m above A, and the pressure at B must be maintained at 138 kPa. If 0.222 m3/s is to flow through the pipe, what must be the pressure at A?
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 reservoir supplies water to a horizontal 6′′ pipe 800 ft long. The pipe flows full and discharges into the atmosphere at the rate of 2.23 cfs. What is the pressure in psi midway in the pipe, assuming the only lost head is 6.20 ft in each 100 ft of length?
Q2. Explain the Memory stack organization of 16 locations of stack( 0 to 15). take the initial value of the
stack pointer is SP = 0E in Hex. Explain the following push and pop instructions through the Memory
stack organization diagram.
(1) PUSH R5 WHERE R5 = XX in Hex
(2) POP R4 WHERE R4 = (XX + 3 ) Hex for example roll no 64 is having the data in R5 = 64
Hex and R4 is ( 64+3 = 67 Hex) [5 marks]

Stone A is hurled vertically upwards from a tower of height h with a speed vA0 . Simultaneously, stone B is thrown vertically upwards from the ground with a speed of vB0.
Given:
h=30m ; vA0=15m/s ; vB0=25m/s ; g=9.81m/s2 Find:
1. At which height and time do the stones fly past another?
2. At this time, what is the speed of stone A relative to stone B?
