(9%) Problem 10: Suppose a Carnot engine has an efficiency of 42.5 % and a cold reservoir temperature of 26-C.Incorrect Answer You have previously used this answer. Please refer to your submission history. 50% Part (a) What is the hot reservoir temperature, in degrees Celsius, of this Carnot engine? h = 247 Correct! Close and stay on this question Partial * 50% Part (b) What must the hot reservoir temperature be, in degrees Celsius, for a real heat engine that has an efficiency of 42.5, which is 70% of the Partial maximum efficiency? Assume it has the same cold reservoir, at 26*C. 7 Completed Grade Summary Th = 723.671 Deductions 9 Potential 100% Partial 10 Partial sin() cos() tan( 7 8 9 HOME Submissions Attempts remaining: 996 cotan() asin() acoso TA 4 5 (0% per attempt) atan() acotan() sinh( 2 3 detailed view 0% cosh() tanh() cotanh() + END WN H 0% O Degrees O Radians VO BACKSPACE DEL CLEAR 0% Submit Hint Feedback I give up!
