Functions

Velocity

Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.

Symbol: v

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.

Formulas to find Velocity

Pelton Head

Pelton Head is the height difference between where the water enters into the hydro system and where it leaves it, measured in meters.

Symbol: H_p

Measurement: LengthUnit: m

Note: Value should be greater than 0.

How to Evaluate Theoretical velocity?

Theoretical velocity evaluator uses Velocity = sqrt(2*9.81*Pelton Head) to evaluate the Velocity, The Theoretical velocity formula is defined from Bernoulli's equation from flow through an orifice. H is the head of the liquid above the centre of orifice. Velocity is denoted by v symbol.

How to evaluate Theoretical velocity using this online evaluator? To use this online evaluator for Theoretical velocity, enter Pelton Head (H_p) and hit the calculate button.

FAQs on Theoretical velocity

What is the formula to find Theoretical velocity?

The formula of Theoretical velocity is expressed as Velocity = sqrt(2*9.81*Pelton Head). Here is an example- 28.7061 = sqrt(2*9.81*42).

How to calculate Theoretical velocity?

With Pelton Head (H_p) we can find Theoretical velocity using the formula - Velocity = sqrt(2*9.81*Pelton Head). This formula also uses Square Root Function function(s).

Can the Theoretical velocity be negative?

No, the Theoretical velocity, measured in Speed cannot be negative.

Which unit is used to measure Theoretical velocity?

Theoretical velocity is usually measured using the Meter per Second[m/s] for Speed. Meter per Minute[m/s], Meter per Hour[m/s], Kilometer per Hour[m/s] are the few other units in which Theoretical velocity can be measured.
