Function for determining strike water temp when brewing burrrr

targetStrike.js

(function getStrikeTemp() {

  const grist = {

    // weight of grist (lbs)
    weight: 17,

    // volume used in mash (gal)
    gallons: 7.61,

    // temperature of the grains (f)
    grainTemp: 74,

    // target mash temperature (f)
    mashTemp: 155
  };


  let modifiedGrist = grist.weight * 0.4,
    waterWeight = grist.gallons * 8.32,
    solution = (((modifiedGrist + waterWeight) * grist.mashTemp) - (modifiedGrist * grist.grainTemp)) / waterWeight,
    strikeTemp = Math.ceil(solution * 100) / 100
  console.log(`****STRIKE TEMP: ${strikeTemp}****`);
