how to calculate a pressure in a sprinkler in javascript

To calculate the pressure in a sprinkler system, you will need to know the flow rate, the pipe size, the length of the pipe, and the number of sprinkler heads. Here's the formula to calculate the pressure:

P = (FL) / (K * C * Q^2)

Where:

• P is the pressure in pounds per square inch (PSI)
• F is the friction loss coefficient, which is determined by the pipe size, length, and flow rate
• L is the length of the pipe in feet
• K is a constant based on the sprinkler head, which is typically between 5 and 10
• C is the number of sprinkler heads on the system
• Q is the flow rate in gallons per minute (GPM)

Here's an implementation of the formula in JavaScript:

index.tsx
function calculatePressure(flowRate, pipeSize, pipeLength, numSprinklerHeads, sprinklerConst) {
   const frictionLossCoeff = getFrictionLossCoeff(pipeSize, pipeLength, flowRate);
   const pressure = (frictionLossCoeff * flowRate * pipeLength) / (sprinklerConst * numSprinklerHeads * Math.pow(flowRate, 2));
   return pressure;
}

function getFrictionLossCoeff(pipeSize, pipeLength, flowRate) {
   // Function to calculate the friction loss coefficient based on the pipe size, length, and flow rate
}

const pressure = calculatePressure(50, 2, 100, 10, 7);
console.log(`The pressure in the sprinkler system is ${pressure} PSI`);

Make sure to implement the getFrictionLossCoeff function to calculate the friction loss coefficient, which can be determined using the Hazen-Williams equation or the Darcy-Weisbach equation, depending on the pipe material and flow velocity.
