400 cumecs of water are being released from dam storage to meet the downstream demand through the turbines of the connected hydro plant. The effective head of water acting on the turbines is 50 m. The efficiency of the hydro plant is 0.8. The electrical power generated from this plant is __________________

400 cumecs of water are being released from dam storage to meet the downstream demand through the turbines of the connected hydro plant. The effective head of water acting on the turbines is 50 m. The efficiency of the hydro plant is 0.8. The electrical power generated from this plant is __________________ Correct Answer 156.8 MW

Using 80% efficiency, Electrical energy = 7.84 QH where H is the design head in meters and Q is the design discharge in cumecs. Electrical energy = 7.84 x 400 x 50 = 1, 56,800 kW = 156.80 MW.

A drainage gallery with its drainage pipe system provided in a gravity dam reduces the uplift pressure at all levels below the upstream water level. 3. An earthquake acceleration of 0.1 g acting vertically downward causes a decrease of 10% in the limit weight of concrete and of water in a gravity dam. 4. The Tehri dam is a gravity dam.

Below stated are some of the statements about the Alternating current. You need to identify which of the following is incorrect, 1. DC power is far more powerful than AC power. The efficiency and power to size characteristics of DC motors and apparatuses are increased. Lighting by DC (LED) is 75% more efficient than lighting from incandescence. 2. A comparatively high voltage alternating current may be generated and easily raised and dropped by the static equipment known as the transformer, which makes electrical energy transmission and distribution economical, 3. Initial costs and maintenance of the AC motor are less expensive since it has no switch and is less powerful than the DC motor for constant working speed, hence it is desired to create power as alternating current. 4. The great efficiency of transmission in ac makes electric power generation cost-effective, Produced in huge quantities in one station and distributed throughout a vast area.
What is the distance covered by boat N upstream in 5 hours? Which of the following option is sufficient alone to find the answer? A) Boat M is travelling downstream with 20% more downstream speed of boat N. Speed of boat M in still water is 10% more than the speed of boat N in still water. B) Boat M and Boat N are travelling downstream with speed 33 km/hr and 40 km/hr respectively and speed of boat M is still water is 2 times the speed of stream. C) Speed of boat M in still water is 6 km/hr less then speed of boat N in still water and speed of stream is 10 km/hr. D) Speed of stream is ½ times the speed of boat N in still water and downstream speed of boat M is 44 km/hr. E) Speed of stream is 10 km/hr and ratio of upstream speed of boat M and boat N is 3 : 2 respectively.
Which of the following statements are correct as regards aquifer characteristics? 1. The storage coefficient is the volume of water released from storage from the entire aquifer due to unit depression of Piezometric head. 2. The storage coefficient is the same as the specific yield for water table aquifer. 3. Both the aquifer constants, viz. storage coefficient S and Transmissivity T are dimensionless numbers. 
The question below consists of a set of labelled sentences. These sentences, when properly sequenced form a coherent paragraph. Select the most logical order of sentences from among the options. P: About 30 new hydro projects are now under execution with an installed capacity of 5,600 MW. Q: However, with the rapid increase in demand for power, a higher priority was given to the pithead super thermal power stations as their gestation period was smaller than that of the hydel schemes. R: Many projects were taken up for execution after independence and at one time (1962-63), the capacity contribution from hydro schemes was equal to thermal schemes. S: The first hydro generating unit in India was commissioned in Darjeeling (W.Bengal) in 1897.
