It has a stationary flow process which uses ammonia as a working substance to produce power. It is a process designed to operate within the ocean at a point where the seawater temperature is 25°C near the surface and 5°C deeper.
A) Determine the power produced by the turbine and the power to be supplied to the pump for this process.
B) Determine the mass flow rate of water passing through each heat exchanger.
It is known that the turbine and pump are isentropic, and that the mass flow rate of ammonia is 100 kg/s

- 11.26** A bead of mass m is threaded on a frictionless circular wire hoop of radius R and mass m (same mass). The hoop is suspended at the point A and is free to swing in its own vertical plane as shown in Figure 11.20. Using the angles 1 and 2 as generalized coordinates, solve for the normal frequencies of small oscillations, and find and describe the motion in the corresponding normal modes. [Hint: The KE of the hoop is 167, where I is its moment of inertia about A and can be found using the parallel axis theorem.] 02 m Figure 11.20 Problem 11.26arrow_forwardPlease solve the question in detailarrow_forward9.
