Question

7-92 FES A thermocouple with a spherical junction diameter
of 1 mm is used for measuring the temperature of
a hydrogen gas stream. The properties of the thermocouple
junction are k = 35 W/m-K, p = 8500 kg/m³, and
c, = 320 J/kg-K. The hydrogen gas, behaving as an ideal gas
Cp
at 1 atm, has a free stream temperature of 200°C. If the initial
temperature of the thermocouple junction is 10°C, evaluate the
time for the thermocouple to register 99 percent of the initial
temperature difference at different free stream velocities of the
hydrogen gas. Using the EES (or other) software, perform the
evaluation by varying the free stream velocity from 1 to
100 m/s. Then, plot the thermocouple response time and the
convection heat transfer coefficient as a function of free stream
velocity. Hint: Use the lumped system analysis to determine
the time required for the thermocouple to register 99 percent of
the initial temperature difference (verify application of this
method to this problem).
