7. A power cycle operating between two thermal reservoirs receives energy QH by heat transfer from a hot reservoir at TH = 1600 K and rejects energy QC by heat transfer to a cold reservoir at TC = 400 K. For each of the following cases determine whether the cycle operates reversibly, operates irreversibly, or is impossible. a. QH = 1000 kJ, ŋ = 75% b. QH = 1100 kJ, Wcycle = 800 kJ c. QH = 900 kJ, QC = 300 kJ

(a) QI = 500KJ, W 350KJ (b) Q1 = 1000KJ, Q2 200KJ (c) W= 800KJ, Q2 = 500KJ (d) 7 = 95 % %3D %3D

Q.2 A Carnot engine operates with ideal gas, using the Carnot cycle shown in the following Figure. Using the first law of thermodynamics and assume no change of internal energy, determine the thermal efficiency, the specific heat impute (q), and the work output (w) for each cycle of operation. (K=1.4 & R=0.287 KJ/Kg. K) T = 220 C 77 kPa T = 20 C 12 m'/kg

pls answer correctly thanks

A power cycle operating at steady state receives energy by heat transfer at a rate Q at T = 1800 K and rejects energy by heat transfer to a cold reservoir at a rate Qc at Tc = 600 K. For each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible. (a) Q₁ = (300) kW, Qc Part A (b) Qu = (500)kW, W cycle = (150) kW, Qc = (200)KW (c) W cycle = (350) kW, Qc = (150) kW (d) Qu = (500)kW, Qc = (100)kW = The cycle is (100) kW Determine whether the cycle operates reversibly, operates irreversibly, or is impossible.

At steady state, a power cycle develops a net power output of 20kW while receiving energy by heat transfer at a rate of 20kJ per cycle of operation from a source at a temperature T. The cycle rejects energy by heat transfer to cooling water at a lower temperature of 5mm K. If there are 1nn (engine thermodynamic) cycles per minute, what is the minimum theoretical value for T, in K?Note: mm=40 nn = mm + 50
