STEP 1: Convert Input(s) to Base Unit

Thickness of Filler Metal: 5 Millimeter --> 0.005 Meter (Check conversion here)
Temperature for Cooling Rate: 500 Celsius --> 500 Celsius No Conversion Required
Ambient Temperature: 37 Celsius --> 37 Celsius No Conversion Required
Density of Metal: 7850 Kilogram per Cubic Meter --> 7850 Kilogram per Cubic Meter No Conversion Required
Specific Heat Capacity: 4.184 Kilojoule per Kilogram per K --> 4184 Joule per Kilogram per K (Check conversion here)
Net Heat Supplied Per Unit Length: 1000 Joule per Millimeter --> 1000000 Joule per Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

τ = t*sqrt(((T_c-t_a)*ρ_m*Q_c)/H_net) --> 0.005*sqrt(((500-37)*7850*4184)/1000000)

Evaluating ... ...
