Unit Speed of Turbine Solution

STEP 0: Pre-Calculation Summary
Formula Used
Unit Speed = (Working Speed)/sqrt(Fall Height)
Nu = (N)/sqrt(H)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Unit Speed - Unit speed is defined as the speed of a geometrically similar turbine working under a head of 1m.
Working Speed - (Measured in Radian per Second) - Working speed of a hydroelectric plant depends on various factors such as the design of the plant, the type of turbines used, the head and flow rate of water, and the desired electrical output.
Fall Height - (Measured in Meter) - Fall height, is an important factor in hydroelectric power generation. It refers to the vertical distance that the water falls from the intake point to the turbine.
STEP 1: Convert Input(s) to Base Unit
Working Speed: 350 Revolution per Minute --> 36.6519142900145 Radian per Second (Check conversion ​here)
Fall Height: 250 Meter --> 250 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Nu = (N)/sqrt(H) --> (36.6519142900145)/sqrt(250)
Evaluating ... ...
Nu = 2.31807059523438
STEP 3: Convert Result to Output's Unit
2.31807059523438 --> No Conversion Required
FINAL ANSWER
2.31807059523438 2.318071 <-- Unit Speed
(Calculation completed in 00.005 seconds)
