An industrial plant requires a steady supply of 3 kg/s of steam at 0.2 MPa and 180°C. The plant is located next to a river whose water is suitable for steam production and also has a reservoir at 400°C. The environment is air at 102 kPa and 20°C. a. Find the least amount of heat that must be taken from the reservoir to produce the required steam. b. Describe schematically a physical system that may perform the task.
