Water at a pressure of 15 bar at a temperature of 30°c enters a boiler, where it is heated to 250°c at constant pressure. steam leaving the boiler passes into a throttle which reduces the pressure to 10 bar. the steam is then passed through a small turbine, exiting at atmospheric pressure at 110°c. draw a schematic diagram. 1. how much heat is added per kg to the water by the boiler? 2. find the temperature of the steam leaving the throttle. 3. if the turbine produces 15kw of work, find the mass flowrate of steam through the system.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
