First and Zeroth Law of Thermodynamics

 First law Of Thermodynamics; To understand thermodynamics well and to make any calculations in thermodynamics, it is extremely important that we have its basic rules. These are some of the basic laws of thermodynamics.The first law of thermodynamics in  will try to understand about this very useful rule through medium. Heat was not considered a form of energy when thermodynamics was developing. But after some time it was proved that heat is also a form of energy, after that an attempt to find a relationship between heat and work started. Heat and work are two different forms of the same entity, and that entity is called energy. This means that if heat is supplied to a system, it can come out as work, or as work is done on a system, it can come out as heat. While the relationship between heat and work came out, a new term introduced the whole world, which was called internal energy. The first law of thermodynamics shows the relation between heat, work and internal energy. F...

Fluid Mechanics "Centrifugal Pumps"

Centrifugal Pumps : we'll just cover certain sections of it, it's on your course syllabus. But we'll start off looking at centrifugal pumps .  A very common type of pump. Swimming pool pumps, spa pumps, all kinds of pumps.  Quite a few of them are centrifugal pumps. I thought so. Okay,sometime this quarter, I don't think this early, you're going to run a test on a centrifugal pump in the fluids lab.  And from that test you're going to put together some performance curves for our centrifugal pump.   So, this is how we  test a centrifugal pump.  I'll go through the procedure that we use in our fluids lab.  We have a pump in a circuit with water in it, from a big reservoir.  The water is pumped through here, it goes around, back into the big reservoir.  We have flow meters in the test setup so we know what the flow rate Q is. We have pressure gauges at points one and two. A centrifugal pump is a radial type of a pump.  There's an impeller ...
