Theory of Rankine Cycle - Equations and Calculation

When latent heat is added, no temperature change occurs. The enthalpy of vaporization is a function of the pressure at which that transformation takes place. Latent heat of vaporization – water at 0.1 MPa (atmospheric pressure) h lg = 2257 kJ/kg. Latent heat of vaporization – water at 3 MPa (pressure inside a steam generator) h lg = 1795 kJ/kg

Miscanthus x giganteus - Wikipedia

Miscanthus × giganteus, the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of more than 4 metres (13 ft) in one season (from the third season onwards). Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass.

Steam Sterilization Principles & Common Mistakes Using

The pressure-temperature relationship values are shown in saturated steam tables.4 A typical cycle at 121°C (250°F) will require 15 to 17 lbs of gauge pressure (103 to 117 kPa) in the chamber of the sterilizer. The gauge pressure required will be higher than the pressure shown in the saturated steam table due to air mixed with the steam and

Boiling water reactor - Wikipedia

A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to
