Number of buckets on runner of Pelton wheel is given by expression? (D-diameter of runner and d- diameter of jet)

Number of buckets on runner of Pelton wheel is given by expression? (D-diameter of runner and d- diameter of jet) Correct Answer 15 + D/2d

To obtain Pelton wheel of higher efficiency, number of buckets is specified as 15 + D/2d by considering several experimental observations.

The given pie chart shows the percentage distribution of the number of buckets sold by a grocery store on different days of a week. And, the number of red buckets sold by the same grocery store on Monday, Tuesday, Wednesday, Thursday and Friday is 225, 150, 175, 75 and 50 respectively. Total buckets sold (in a day) = Red buckets + Green buckets Total buckets sold by a grocery store in the given days = 1250 What is the ratio between the total number of red buckets sold on Wednesday and Thursday together to the total number of green buckets sold on Thursday and Friday together?

Water, having a density of 1000 kg/m3, leave from a nozzle with a velocity of 10 m/s and the jet strikes a bucket mounted on a Pelton wheel. The wheel rotates at 10 rad/s. The mean diameter of the wheel is 1 m. The jet is split into two equal streams by the bucket, such that each stream is deflected by 120°, as shown in the figure. Friction in the bucket may be neglected. Magnitude of the torque exerted by the water on the wheel, per unit mass flow rate of the incoming jet, is
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?
