The temperature of a flowing gas stream is measured using a thermocouple, which is a spherical metal bead 1.5 mm in diameter. The properties of the metal are p=9000 kg/m³ , C₂ = 550 J/kg-K and k=30 W/m K. The film coefficient between the gas and the metal is 410 W/m².K. If the gas temperature is suddenly increased from 300 C to 310 °C, how long will it take for the thermocouple to reach 308 C? a) 5 sb) 2.56 sc) 3.55 sd) 4.95 s |
