Unformatted text preview: c) Determine the work output of the cycle. d) Find the thermal efficiency of the cycle. Page 1 of 1 Problem 2: The following device operates at steady-state and is well insulated. Air enters at one location and exits at another with a mass flow rate of 10 kg/s. Assuming perfect gas behavior and negligible potential energy effects, determine the direction of the air flow and the direction of the power flow. Determine the power in kW. Assume cp=1000 J/kgK for air. (Hint: it might be useful to initially assume directions of the different energy fluxes and then to check for consistency.) Page 2 of 2...
