The existing thermocouple has the following design data:
• Material: AISI 304 Stainless Steel
• Shape: Spherical (2 mm diameter)
• Heat transfer coefficient: h =
2.2(V/D)0.5
• Time to 0.99 A T: 18 seconds
• Minimum flow velocity: 43 m/s
Verify the performance of the existing thermocouple
• Check that for a minimum velocity of 43 m/s you can reach 99% of the T value at the center of the
thermocouple in 18 seconds
