please written solution by hand and how can com h6 and s6 when T turbine inlet = 130 C , P heat exchanger = 20 bar , P condenser = 5 bar , Tw . cond out = 25 C Tw cond in = 17.5 C efficiencies compressor = 67.5 efficiencies turbine = 78 m. refrig =0.4 kg/s
In a steam turbine system, suppose the value of ∆mH is constant (meaning, inlet and outlet conditions are maintained). From the energy balance equation, Qnet + Wnet = ∆mH + ∆KE + ∆PE or −0.1209 kW − 70 kW = ??̇? + 8.75 kW − 0.0068kW 1. What will happen to Wnet if there was no increase in kinetic energy, will the magnitude of Wnet increase or decrease? What should be the sign of potential energy so that Wnet will increase in magnitude?2. For a turbine system, what should happen to Qnet, ∆KE, and ∆PE to maximize the work done by the turbine? Which factor is the most significant?
THA= 31 Celcius Degree TLA= 8 Celcius Degree QLA= 72 kW WA= 12 kW THB= 33 Celcius Degree TLB= 4 Celcius Degree QLB= 36 kW WB= 6 kW
As shown in the figure below, a reversible power cycle receives energy QH by heat transfer from a hot reservoir at TH and rejects energy Qc by heat transfer to a cold reservoir at Tc. Hot reservoir at TH Boundary- Cold reservoir 20 at Te (a) If TH = 1100 Kand Tc = 400 K, what is the thermal efficiency? (b) If TH = 500°C, Tc= 20°C, and Weycle = 1800 kJ, what are QH and Qc, each in kJ? (c) If n = 70% and Tc= 40°F, what is TH, in °F? (d) If n = 40% and TH = 1027°C, what is Tc, in °C?

* İl. Gmail ► Untitled docu.. A system consists of a turbine and heat exchanger are connected in series. The working fluid is entering the turbine at P1 0.6 Mpa, T= 200 °C and leaving it with P,= 0.2Mpa. Then the turbine exit becomes the heat exchanger inlet to increase the fluid temperature to become 800 °C. Considering that the adiabatic power y =1.4 and the specific heat = 1.005 KJ/Kg.K. Determine the turbine production work WT and heat exchanger energy needed to be added quE. T = 200 °C P,= 0.6 Mpa- T T2 ? P,=0.2 Mpa h high НЕ T= 800 °C P3 =? 9 in
