Problem 78P

Problem 78P

 A heat engine operates between a source at K W 477°C and a sink at 25°C. If heat is supplied to K the heat engine at a steady rate of 65,000 kJ/min, determine  the maximum power output of this heat engine.

Step-by-Step Solution:
Step 1 of 3

MATH 2450 WEEK 7 Strategy On a close domain, look for all critical points inside the domain. Look for the boundary points then compare. Look for all critical points inside the domain: F = 0 x Fy= 0 Look for all critical points on the boundary g’(t) = 0 Look at the boundary points of the boundary EX. Find the absolute max/min f(x,y) = e(2) - over the disk x + y <= 1 1) x + y < 1 2) x + y = 1 x^(2) - y^(2) Fx= 0  2xe = 0  x = 0 x^(2) - y^(2) Fy= 0  -2ye = 0  y = 0 Po= (0,0) Forms of absolute minimum and maximum 1) Y = sqrt(1-x ) -1<= x <= 1 Y = -sqrt
