3) A stainless steel jacketed temperature probe is used to measure hot water temperature in a pipe. The properties of the of the stainless steel are: thermal conductivity k=16W/mK,=8000kg/m3,Cp=2.kJ/kgK. At the normal wate flow rate a heat transfer coefficient (h) of 580W/m2K is estimated. The stainless steel jacket has a wall thickness of 2.5mm (can assume slab geometry). For a sudden change of fluid temperature of 10C estimate the time for the thermocouple to measure a temperature change of 9C
