Scenario
A manufacturer of helicopter blades heat-treats a part as one of the steps of the processing procedure. Heat-treating involves heating the metal up to a
highly specific temperature and then quenching, or cooling, it down quickly. The blades are made from an aluminum alloy and have a mass of 273 kg.
Water is normally used for the quenching phase. If the water is at a temperature of 22°C, how much water (in kg) would be needed to cool the blade
from 300°C to at least 50°C?
External Data
The Cp of water is 4,180 J/kg °C, and the C, of aluminum alloy is 900 J/kg °C. The equation for calculating heat gained or lost by a material is q = mCAT.
