Jet Ratio of Hydroelectric Power Plant Solution

STEP 0: Pre-Calculation Summary
Formula Used
Jet Ratio = Bucket Circle Diameter/Nozzle Diameter
J = Db/Dn
This formula uses 3 Variables
Variables Used
Jet Ratio - Jet ratio (m) is the ratio of Diameter of Pelton wheel to the diameter of the jet of water.
Bucket Circle Diameter - (Measured in Meter) - Bucket circle diameter is the diameter of the circle that is formed by the tips of the turbine blades or buckets as they rotate.
Nozzle Diameter - (Measured in Meter) - Nozzle diameter is an important parameter in hydroelectric power plants as it affects the flow rate of water through the turbine and ultimately determines the amount of power that can be generated.
STEP 1: Convert Input(s) to Base Unit
Bucket Circle Diameter: 1.23 Meter --> 1.23 Meter No Conversion Required
Nozzle Diameter: 0.082 Meter --> 0.082 Meter No Conversion Required
STEP 2: Evaluate Formula
