Impulse turbines are used for high head and low flow while reaction turbines are used for low head and high flow.

• Impulse turbines have fixed nozzles while reaction turbines have moving blades.

• Impulse turbines are more efficient at high speeds while reaction turbines are more efficient at low speeds.

• Examples of impulse turbines include Pelton and Turgo turbines while examples of reaction turbines include Francis and Kap

Scaling formation in turbines refers to the buildup of mineral deposits on the turbine blades and other components.

• Scaling formation can reduce the efficiency of the turbine and increase maintenance costs.

• It is caused by minerals in the water supply that accumulate on the turbine components over time.

• Regular cleaning and maintenance can help prevent scaling formation.

• Chemical treatments can also be used to dissolve or ...read more

Staff readings can determine the elevation difference between points.

• Staff readings involve using a leveling instrument, such as a level or a theodolite, to measure the vertical distance between two points.

• A high point is determined when the staff reading at that point is greater than the staff reading at a nearby lower point.

• A low point is determined when the staff reading at that point is smaller than the staff readi...read more

Back bearing is the opposite direction of a forward bearing.

• Back bearing is the bearing taken in the opposite direction of a forward bearing.

• It is used in surveying to determine the direction from a point back to a previous point.

• Back bearing is measured in degrees clockwise from the north or south direction.

• It is commonly used in traversing and resection calculations.

• For example, if the forward bearing from point A to...read more

W.B.M. stands for Water Bound Macadam, which is a type of road construction method using crushed stones and water.

• W.B.M. is a type of road construction method where layers of crushed stones are compacted and bound together with water.

• It is commonly used for rural roads and low traffic volume roads.

• The thickness of each layer and the size of the stones used can vary depending on the specific requirements of the road.
