An ideal Rankine cycle uses water as a working fluid. The water circulates at a rate of 80 kg/s. The boiler pressure is 6 MPa, and the condenser pressure is 10 kPa. The water enters the turbine at 600°C and leaves the condenser as a saturated liquid. Assume that heat is transferred to the working

Water is the working fluid in an ideal Rankine cycle. Superheated vapor (steam) enters the turbine at 100 bar and 480°C. Saturated liquid exits the condenser at a pressure of 0.06 bar. The mass flow rate of the steam flowing in the system is 80 kg/s. P = 100 bar T = 480°C Boiler Turbine

The forces acting on the aircraft during the flight are shown in the diagram below. Determine the resultant of four forces and its line of action with respect to the axis of the plane which is the angle making with either \”x\” or \”y\” planes. y x Thrust 15 kN 35 kN Lift 8Drag 5

How can I create an extended free body diagram of an aircraft during the cruise stage of flight (equilibrium)? The free body diagram should have all the main four forces such as Lift, Weight, Thrust, and Drag. What confuses me is that the question asks to add the tailplane as a vector force (the tailplane

what two numbers multiply to be -56 and add up to be -1? The Correct Answer and Explanation is: Step 1: Understand the problem We are given two conditions: This tells us we are looking for two integers that, when multiplied together, give –56, and when added together, give –1. Step 2: List factor pairs
