Consider the following statements:1. Surge tanks are not substitute for forebays.2. Pumped storage power plants are a boon to power generation.3. Water hammer in penstocks is not dangerous.4. Kaplan turbines are used in low head power plants.Which of the above statements are correct?
A hydraulic turbine develops 8000 kW when running at 300 rpm under a head of 45 m. the speed of the same turbine under a head of 60 m is
Pick the correct order of various turbines with respect to specific speed.
A water turbine delivering 10 MW power is to be tested with the help of a geometrically similar 1 : 10 model which runs at the same speed and efficiency. The power developed by the model will be:
In general sense, water turbines may be put in the following decreasing order of specific speeds as
Consider the following statements in connection with hydraulic turbines:1. The Kaplan turbine is a radial flow turbine in which the guide vane angles as well as the runner vane angles are adjustable.2. Francis and Kaplan turbines are provided with draft tubes which carry water from exit of runner to tail water to increase the gross head across the turbine.3. The parts of turbines susceptible to cavitation are the guide vanes and runner vanes – drastically reducing the turbine efficiency.4. The specific speed of a 4-jet Pelton turbine will be 28 if the specific speed of a single-jet Pelton turbine is 14.Which of the above statements are correct?
Manometric head developed hm in m, and discharge Q in lps n respect of two pumps, 1 and 2, are tabulated. The pumps are connected in series against a static head of 100 m. Total head losses for a discharge of Q are as \(\frac{{{Q^2}}}{{100}}\left( m \right).\) What is the delivered discharge?Q in lps1518202225Hm1 in m60.661.262.055.048.0Hm2 in m50.851.048.845.840.0

Hydroelectric power plant is
Consider the following statements regarding a turbine:1. Specific speed plays an important role in the selection of the type of turbine.2. An increase in specific speed of the turbine is accompanied by higher maximum efficiency.3. The runner of too high specific speed with high available head increases the cost of the turbine on account of the high mechanical strength required.Which of the above statements are correct?
