Chapter 5, Problem 5.23CU

Thermodynamics subject power cycles. Show the ts diagram and complete and step by step solution. Bix the final answer.

Describe the Carnot Principles and briefly discuss the importance.

The following processes occur in a reversible thermodynamic cycle: 1-2: 0.2 kg heating at constant pressure 1.05 bar at specific volume 0.1 m3/kg and work done -515 J. 2-3: Isothermal compression to 4.2 bar. 3-4: Expansion according to law pv1./= constant. 4-1: heating at constant volume back to the initial conditions. Using file 3, which figure number is associated the process? ?

Hi, I need to go over this problem, but how do you find To and Po. Can you walk me through every question that I state on the paper? Thanks

Thermodynamics, please help with part 2 and show all work

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. (a) If TH = 1600 K and TC = 400 K, what is the thermal efficiency?(b) If TH = 500°C, TC = 20°C, and Wcycle = 1000 kJ, what are QH and QC, each in kJ?(c) If η = 70% and TC = 40°F, what is TH, in °F?(d) If η = 40% and TH = 1027°C, what is TC, in °C?

Calculate Carnot efficiency, Rankine efficiency, condenser heat flow in kW assuming mass flow rate of steam as {D} kg/s and steam rate for each case considering the pump work. (i) Dry and saturated Wet with 0.95 dryness (ii) (iii) Superheat at {C}°C A=20 B= 0.5 C= 400 D= 11 Solve the problem by both steam tables-and Mollier diagram for all the cases.

P.4 (Application on the First Law of Thermodynamics with heat transfer) A silicon chip measuring 5 mm on a side and 1 mm in thickness is embedded in a ceramic substrate. At steady state, the chip has an electrical power input of 0.225 w. The top surface of the chip is exposed to a coolant whose temperature is 20°C. The rate of energy transfer by heat between the chip and the coolant is given by 9= hA (T, - T), where T, and T, are the surface and coolant temperatures, respectively, A is the surface area, and If heat transfer between the chip and the substrate is negligible, determine the surface temperature of the chip, in °C.
