Uses Of Calculus In Other sciences A Mechanical Engineer Uses calculus in his job like ( Differential Calculus, Integral Calculus, Multivariable Calculus). My example will be about mechanical engineer Heat transfer calculations. For Heat transfer calculations they use q = m(DT)Cp Where : 1. q = heat transferred, 2. DT = the change in temperature 3. Cp = the specific heat.

Uses Of Calculus In Other sciences Example: Aluminum has a specific heat of J/g x o C. How much heat is lost when a piece of aluminum with a mass of g cools from a temperature of o C to a temperature of 22.0 o C? Step 1: Write the original formula. q = m(DT)Cp

Uses Of Calculus In Other sciences Step 2: List the known and unknown factors. Looking at the units in the word problem will help you determine which is which. q = ? m = g DT = (415.0 o C o C) = o C (remember, they asked for the change in temperature) Cp = J/g x o C

Uses Of Calculus In Other sciences Step 3 : Substitute your values into the formula q = m(DT)Cp q = g x o C x J/g x o C Step 4: Cross out units where possible, and solve for unknown. q = g x o C x J/g x o C q = J q = 8.50 x 10 3 J

I cant believe that we did it!
