What is flow and non flow process of themodynamic's?
flow process : it is one in which fluid enters the system and leaves it after work interaction,which means that such processes occur in the systems having open boundary permitting mass interaction across the system boundary. non flow process : it is the one in which there is no mass interaction across the system boundaries during the occurrence of process. different type of non flow process of perfect gas are given below: (1) constant volume process (2) constant pressure process (3) Isothermal process (4) adiabatic process (5) polytropic process
Why is SI easier than the English system?
Most measurements are more of habits learned than anything else. So, a yard vs a meter is only what one is used to dealing with.The metric system has a couple of advantages. It is based on the decimal system, with standardization of units and prefixes. It makes comparisons from one unit to another easier and more logical.It is "logical" that 1cc = 1ml. 1 liter water (very common) = 1 kg, etc.The "English" system has different bases from 12 for inches to 5280 feet per mile. Cups, pints, quarts, teaspoons, tablespoons, etc are all somewhat obscure measurements. There are even different sizes of gallons depending on what substance one is discussing, or which country a person is in.However, not all is bad with the "English" system either. Fractions can be logical. Halves, Quarters, Eighths, Sixteenths, etc. often just make sense.And, while Fahrenheit isn't based on freezing and boiling of water, it is based more or less on a "normal" temperature range that people are likely to experience. I.E. in much of the world, 0°F is very cold, and 100°F is very hot. Anything falling outside of that range would be considered extremes.But, then again, perhaps that is just a habit, and it would be equally logical to think of -10°C being chilly and 40°C being hot.The reason why many who use the metric system prefer it, was summed up by one contributor in this way:"The metric system is based on tens, hundreds and thousands - simplicity itself. The Imperial system uses threes (feet in a yard), eights (pints in a gallon, also furlongs in a mile), twelves (inches in a foot), fourteens (pounds in a stone), sixteens (ounces in a pound and also fluid ounces in an American pint), twenties (fluid ounces in a British pint) - need I say more???"
