k=25 W/mK Stainless Steel a=0.6*10-5 m²/s The temperature of a stainless steel sphere (D=10 mm) is measured over time in a hot water bath. The initial temperature of the sphere is T₁ = 25°C and the ambient temperature of the surrounding water is Too = 85°C The convection coefficient of the surrounding water is W h = 900- mK . Using these parameters, what is the Biot Number of the system? 0.36
ers What is the Fourier Number at time t-30s? 1.8 2.16 (with margin: 0)
d What is the specific heat of the stainless steel sphere (in J/kgK)? Assume p = 7930kg/m³ 9.63
ers What is the thermal time constant ( T ) of the system (in seconds)? Between 7.7 and 7.9
d What is the temperature of the sphere at time t = t (in Celsius)? 32
