WebQ3 A generator has a 500 MW output power and a 95% efficiency. The generator is located in ambient air temperature of 33°C. Rth = 6x10-6 K/W Cth = 70x10+6 J/K a. Calculate the time after the generator is switched on for the generator's temperature to reach 125 °C. b. Calculate the generator steady-state temperature. WebWhat time constant - Cth Rth is needed so that a 1 kW electrical system which is 90% efficient reaches its steady- state temperature within 5 time constants. The ambient air …
WebMay 21, 2024 · The relative transit time heterogeneity (RTH equal to CTH/MTT), tends to remain constant across brain tissue types in healthy subjects. 15, 30 We generated maps of RTH in our subjects to examine whether RTH is altered in MCI. While GE-based MTT, CTH, and RTH measurements are expected to reflect perfusion and perfusion heterogeneity … WebIt is calculated by multiplying the Cth & Rth. The stator takes much more time to heat up than the coil due to its larger thermal capacitance Cth(s) and higher thermal resistance Rth2 and hence has a comparatively much higher thermal time constant value. For the coil, the thermal time constant is in the range of seconds to minutes depending on ...
