1. Difference betwixt 'Thermodynamics together with Heat Transfer'
- Thermodynamics mainly deals alongside the transfer of unloosen energy inwards cast of oestrus or piece of job between systems together with surroundings with other systems inwards cast of either oestrus or piece of job inwards equilibrium conditions. When at that spot is modify inwards 1 state, which was inwards equilibrium acre together with starting to modify inwards other equilibrium state, this information helps to decide oestrus or piece of job interactions due to this process. While
- Heat transfer deals alongside non equilibrium oestrus central or transfer due to temperature slope piece inwards thermodynamics, during thermal equilibrium (No temperature gradient) no oestrus central is possible. [Read to a greater extent than interview questions on Thermodynamics]. Heat never transfer when at that spot is no temperature gradient.
2. Difference betwixt Pipe together with tube
- There e'er a combat betwixt differentiation of pipe together with tube. Pipe is e'er designated yesteryear its Inside Diameter (ID) because master copy purpose of pipage is to comport fluid, piece the
- Tube is e'er designated yesteryear its Outside Diameter (OD). Pipe's thickness is sometimes called equally schedule together with tube's thickness is gauge.
- As per the tolerance basis, tubes requires higher tolerances equally to that of pipage together with tubes are to a greater extent than costlier inwards manufacturing compared to pipage production.
3. Difference betwixt Flywheel together with Governor
4. Difference betwixt tempering together with annealing
Annealing is a procedure inwards which workpiece is heated upwards to for sure temperature to larn desired changes inwards grain or micro-structure together with and thence allowed to cool slow inwards club to preserve the stresses during piece of job treatment. While tempering is a procedure wherein hardness together with elasticity or ductility tin live find yesteryear utilization of heating together with cooling bicycle till desired properties tin live obtained.
