A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 4 MPa in the boiler and 20
kPa in the condenser and a turbine inlet temperature of 700°C. The boiler is sized to provide a steam flow of 50 kg/s. Determine the power produced by the turbine and consumed by the pump.
Answer: Explanation: Application of the bernoulli's equation comes in from conservation of mass flow. The cross sectional area of the two pipes are calculated. from A = πD²/4
The velocity of water from conservation of mass flow is also calculated ; V2 = Ac1V1/Ac2
The Loss coefficient is then calculated from KL = (1 - Ac1²/Ac2²)²
Then the head Loss (hL) is calculated The detailed calculated and appropriate steps is as shown in the attached files.
Valleys and low-lying areas, hills and mountains, were some of the challenges faced by Roman engineers who built Aqueducts. The first aqueduct was built in Rome around 312 BC. By the 3rd century AD, it became common.
