Use the jacobi method to solve for p. your initial guess should be a 90 × 1 vector of all ones, and you should use a tolerance of 10−5 . your tolerance check should use the infinity-norm, i. e., norm(xkplus1 - xk, inf) < tol. calculate the error by subtracting the final iteration of the jacobi method, pjacobi, from the "exact solution" obtained in part (b), pexact, and then taking the 2-norm of the difference: error = kpexact − pjacobik2.

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
