Number of Jets Solution

STEP 0: Pre-Calculation Summary
Formula Used
Number of Jets = (Specific Speed of Multi Jet Machine/Specific Speed of Single Jet Machine)^2
nJ = (NSMJ/NSSJ)^2
This formula uses 3 Variables
Variables Used
Number of Jets - Number of jets in a hydroelectric power plant can vary depending on the design and size of the plant. The jets are used to control the flow of water through the turbines, which generate electricity.
Specific Speed of Multi Jet Machine - (Measured in Radian per Second) - Specific Speed of Multi Jet Machine is defined as the speed at which a geometrically turbine of unit size would operate if it were capable of delivering one unit of power at a head of one unit.
Specific Speed of Single Jet Machine - (Measured in Radian per Second) - Specific Speed of single jet machine is the speed at which the turbine would run if it were geometrically to a unit turbine having a diameter of one meter and a head of one meter.
STEP 1: Convert Input(s) to Base Unit
Specific Speed of Multi Jet Machine: 73.49 Revolution per Minute --> 7.6958548033519 Radian per Second (Check conversion here)
Specific Speed of Single Jet Machine: 30 Revolution per Minute --> 3.14159265342981 Radian per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
nJ = (NSMJ/NSSJ)^2 --> (7.6958548033519/3.14159265342981)^2
Evaluating ... ...
nJ = 6.00086677777779
STEP 3: Convert Result to Output's Unit
6.00086677777779 --> No Conversion Required
FINAL ANSWER
6.00086677777779 6 <-- Number of Jets
