Why v = 2πr÷T |
|
Answer» V=S/T where she is displacement and when particle moving inside the circle it\'s displacement =2(pie)r/Time V=distance/time so 2(PIE)r=circumference i .e distance travelling by particle when revolving around a circle.thus v=2 (pie)r/T where 2(pie)r=distance and T=time |

What is turbulent force |
|
Answer» When a liquid velocity exceeds critical velocity the flow is said to be turbulent or zip zag Turbulent flow, type offluid(gas or liquid) flow in which the fluid undergoes irregular fluctuations, or mixing, in contrast tolaminar flow, in which the fluid moves in smooth paths or layers. In turbulent flow the speed of the fluid at a point is continuously undergoing changes in both magnitude and direction. The flow of wind and rivers is generally turbulent in this sense, even if the currents are gentle. The airor water swirls and eddies while its overall bulk moves along a specific direction. |

What is cp and cv |
|
Answer» Cp is basically greater than cv Basically gases have two specific heats..... One is Cp i.e. specific heat at constant pressure , where the system is applied heat by keeping its pressure constant. And another is Cv, i.e.specific heat at constant volume, where again the system is supplied heat by keeping the volume constant. |
