A welder has just welded two pieces of carbon steel together and needs to quench the weld in a water bath down to room temperature (68°F).What is the minimum volume (gal) of water necessary to cool the 400°F weld down to thermal equilibrium?
Remember: Convert °F to °C
Conversions:
(°F - 32) x5/9 = °C
1 gal = 3.78541 L
1 lb = 0.453592 kg
Additional Knowns:
Cpwater = 4184 J/kg°C
msteel = 2 lbs
Tinitial water= 50°F
Cpsteel= 620 J/kg°C
