4 8 16 In the first call to the function, we only define the argument a, which is a mandatory, positional argument.In the second call, we define a and n, in the order they are defined in the function.Finally, in the third call, we define a as a positional argument, and n as a keyword argument.. If all of the arguments are optional, we can even call the function with no arguments.

Step 2: Use the accessory measuring cup to take out pure water (with a funnel) not exceeding 300ML, and pour the water into the boiler of the machine. Step 3: Tighten the safety helmet, and replace with a suitable spray head according to cleaning needs. Step 4: Turn on the power, the red light is on and mini steam cleaner is heating.

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.

As Low as Reasonably Practicable (Process Safety) - an

The ALARP (as low as reasonably practicable; see Figure 38.5) principle is sometimes used in the oil and gas industry (UK HSE, 1992).The use of the ALARP principle may be interpreted as, satisfying a requirement to keep the risk level as low as possible provided that the ALARP evaluations are extensively documented.

The steam temperature is a function of the steam pressure. Water boils at 100° C at 1 atm., but at other pressures the boiling point changes. At its boiling point, the steam condenses in the coils and gives up its latent heat. If the steam temperature is too high, burn-on/fouling increases so there are limits to how high steam temperatures can go.

Heat is supplied externally to the boiler for steam generation depending upon state of s team desired. Boiler may be assumed similar to a closed vessel having no work interaction, no change in kinetic energy, no change in potential energy. i.e. W = 0, .KE = 0, .PE = 0.

Organic Rankine cycle - Wikipedia

The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, screw, scroll, or other expander), and then through a condenser heat exchanger where it is finally re-condensed.. In the ideal cycle described by the engine's theoretical model, the expansion is
