Rankin ‘A’ by K.R. Gammie, we are told that the operating temperature for a 1 year flowing condition, the temperature is 76°C and has a pressure of 24.2 MPa. At this flowing condition, we can see that we have a point far above the saturation dome; therefore the fluid is single phase. For a 10 year flowing condition, the temperature is given as 96°C and has a pressure of 13.2 MPa. At this flowing condition, we have a point that is just inside the saturation dome which means that the fluid is in 2 phases

COMBINED GAS LAW SUMMARY The combined gas law is a gas law which combines Charles's law, Boyle's law, and Gay-Lussac's law. This law states: “The ratio between the pressure-volume product divided by the temperature of a system remains constant.” This can be stated mathematically as:  Where: p is the pressure, V is the volume, T is the temperature measured in kelvins, and k is a constant (with units of energy divided by temperature). Reminder: 1atm= 760 torr = 101.3 kPa & Celsius to Kelvin=

SIMPLE SCIENCE EXPERIMENTS HANS JURGEN PRESS 1. Astronomy Image of the Sun Place a pair of binoculars in an open window in the direct path of the sun’s rays. Stand a mirror in front of one eyepiece so that it throws an image of the sun on to the opposite wall of the room. Adjust the mirror until the image is sharp, and darken the room. You would risk damaging your eyes if you looked directly at the sun through binoculars, but you can view the bright disc on the wall as large and clear

Master Diver Diving Equipment Open circuit demand scuba is the most commonly used by recreational divers, but closed circuit and semi-closed rebreathers are now available. Test Pressure: the pressure to which the cylinder is subjected to during hydrostatic testing. For a 200 bar cylinder it is 300 bars, for a 232 bar cylinder it is 348 bars. If internal inspection reveals corrosion, it may have to be cleaned by tumbling. The tumbling process involves filling the cylinder approximately

saturated liquid refrigerant-134a. The piston is free to move, and its mass is such that it maintains a pressure of 900 kPa on the refrigerant. The refrigerant is now heated until its temperature rises to 70oC. Calculate the work done during this process. The freely-moving piston can be interpreted as giving a constant pressure process such that P1 = P2 = P = 900 kPa. For a constant pressure process, the concept that the work is the area under the path is particularly simple. That area is a rectangle

subjected to internal pressure. This experiment aids the understanding of how a cylinder withstands internal pressures and how the behaviour of stresses varies at different points along the cylinder radius. Theory Using Lame's equations for a thick cylinder subjected to an internal pressure, the following equations, based on pressure and geometry, may be obtained to calculate hoop and radial stresses: σθ= PK2-1(1+ R22r2) σr= PK2-1(1- R22r2) Where: P = Internal pressure R1 = Internal radius
