Advanced Fluid Mechanics

Midsemester Test 1

Time : 2 hours Max. Marks : 40 Answer all questions 1. Design the pelton turbine for the following data

Head : 200m; power developed 748 kw; speed = 300rpm, Cv = 0.98, o=90%(7)

2. A pipeline of 60cm diameter is 1.5 km long. In order to increase it

discharge, another parallel line of the same diameter is introduced in the

second half of length. Neglecting the minor losses, find the increase in

discharge. Take f=0.02. The head at inlet is 30m. (7)

3. Two reservoirs 5.2 km apart are connected by a pipe line which

consists of a 225mm diameter pipe for the first 1.6km, sloping at

5.7m per km. For the remaining distance, the pipe diameter is

150mm laid at a slope of 1.9m per km. The levels of water above

the pipe opening are 6m in the upper reservoir and 3.7m in the

lower reservoir. Taking f=0.02 and Cc=0.6, calculate the rate of

discharge.

(6)

4. A single acting pump of 25cm bore and 40cm stroke delivers

water through a 10cm diameter delivery pipe to a tank located at

15m above and 20m horizontally from cylinder. If separation occurs

at 2.3 m of water absolute, find the maximum permissible speed at

which the pump can run without separation for the following two

conditions (i) the delivery pipe is horizontal from the pump and then

vertical (ii) the delivery pipe is vertical from the pump and then

horizontal. Take atmospheric pressure is 10.3m of water.6

5. A centrifugal pump is running at 500rpm and discharging 8m3/min

against a head of 10m. It has an impeller diameter of 50cm and

inner diameter 25cm. Vanes are set back an outlet angle of 450. The

constant flow velocity is 2m/sec. Determine manometric efficiency,

vane angle at inlet and minimum starting speed. (6)

6. Draw the neat sketches of various draft tubes and explain its

functions. (4)

7. Explain briefly about water hammer. (4)

Mapping of Assignment

1. Following data refers to Francis turbine. Design the turbine

Head = 50m, speed = 540 rpm; Output power: 295kw; h=95%, o=85%,

Flow ratio =0.15, Breadth ratio =0.1; Inner diameter to outer diameter=0.5

and 5% circumferential area is occupied by vanes; velocity of flow is

constant.

2. Explain briefly about the governing of turbines with a neat sketch.

3. Two reservoirs are connected by a pipe of 800m long. The pipe goes

over a hill whose height is 6m above level of water in the upper reservoir.

The pipe diameter is 300mm and f=0.02. The difference in water level of the

reservoirs is 12.5m. If the pressure of water anywhere in the pipe is notallowed to fall below 1.2m of water. Calculate the length of inlet leg. Also

find the discharge. The absolute pressure is 10.3m of water.

4. A centrifugal pump is running at 500rpm and discharging 8m3/min against

a head of 10m. It has an impeller diameter of 50cm and inner diameter

25cm. Vanes are set back an outlet angle of 450. The constant flow velocity

is 2m/sec. Determine manometric efficiency, vane angle at inlet and

minimum starting speed.

5. Test on a turbine runner is 1.25m in diameter at 30m head gave the

following results. Power developed 1000kw. RPM =180 and discharge

2.7m3/sec. Find the diameter, speed and discharge of a runner to operate at

45m head and give 2000kw at the same efficiency.

6. A triangled pipe net work ABC having the following properties. Find the

rate of flow in each pipe. Flow entering at A is 150cumecs. Kab=2; Flow

coming out from B is 75 cumecs. Kbc=3. Flow coming out from C is 75

cumecs. Kca=3.
