5. ## What is a manometer?

Manometer is 'U' tube pipe which is used for measuring the pressure difference between two points. The difference is denoted by 'h' . From this h value flow flowing through pipe is measured. By the formula Q=a1a2√2gh ---------------- √a1²-a2²

7. ## Khan Aatif Liyaqat Ali

Can anyone Tell me about the difference between Plummer and Pillow Block?What is it?

8. ## Introducing Engineering Subjects study clubs

I think during starting phase it is good .Later it can be updated as per the need of members.

18. ## What is power factor?

Power factor is the cosine of the angle between the voltage and the current. It is the third factor in the product that expresses the power, P = V*I*cos(phi) where phi is the phase angle. DrD
19. ## What are real, reactive, and apparent power?

Real power is just what it says, power as in work done per unit of time. In electrical systems, the real power is calculated as Preal = V*I*cos(phi) where V = voltage I = current phi = phase angle between current and voltage Reactive power is Preact = V*I*sin(phi) I've never heard the term "apparent power" but I suspect what you mean is what I know as Volt-Amperes = V*I The real power is the in-phase part of the volt-ampere product while the reactive power is the out-of-phase part of that product. DrD
20. ## Why are all cores exposed to ac flux variations laminated?

Ths is done to reduce eddy current losses by preventing current flow perpendicular to the laminations. The laminates are electrically insulated from each other (usually by varnish) which blocks current flow while allowing magnetic flux to flow freely. DrD
21. ## Just how does a decrease in flux produce an increase in speed in a linear machine?

This process is called "field weakening" and it was used for speed control on the ancient rolling mill where I worked long ago. As the field current is reduced, flux must be cut more rapidly to maintain the back EMF. The only way this can happen is for the rotor to turn more rapidly, thereby cutting more flux per unit of time. DrD The term "linear machine" seems ambiguous to me. I think you intend to describe an electrical machine (motor) described by linear differential equations. The term can also be used to describe an electric motor for which the moving element translates rather than rotates. For a translating induction machine, the usual acronym is LIM, Linear Induction Machine. Such machines can also be built in synchronous form, known as LSM, Linear Synchronous Machines. The linear machines of this sort are being used to launch aircraft from aircraft carriers. DrD
22. ## Mechanics of Machines, 2nd ed - free textbook

I hope that a great many folks will download this file. It is better than that previously posted, and probably my last effort. It is not yet available at Lulu.com, but I hope to eventually make that happen. It seems inappropriate to rate my own book, but it is required by the website. DrD

Okon, I'm not sure I can answer your question fully, but I will try to give you some hints. First, we refer to "brake" (to stop a vehicle), not "break" ( to disconnect or to come apart). Second, the brakes should work properly with or without ABS operating. ABS will try to correct for one or more wheels sliding while braking in order to maintain steering control. You could have one of several problems: 1) air trapped in the brake lines - will make the pedal feel "spongy". Bleeding the brake lines is a tricky job best left to an expert mechanic. 2) faulty master cylinder - this is the heart of the system - when you press the brake pedal, you develop pressure that is distributed to all four wheels. If the master cylinder leaks, you could get good pressure when you first press the brake pedal, and then lose pressure as you hold the pedal down. If that were the case, your ABS would not work well either, because it relies on the master cylinder to maintain pressure. Finally - one or more wheel cylinders (that actuates the drum or disc) could leak - this might cause similar issues as faulty master cylinder. ( Look up "Hydraulic brake system" online to see a diagram of the system and to understand how the parts interact). You do not state how many miles are on the vehicle and the brake system. If it is a high number, the brake wear may have allowed the wheel (piston) to extend to a part of the cylinder which is not worn as much, or corroded so that the hydraulic seal is not good. If you have installed new discs or drums, you might have to rebuild the wheel cylinders. This is not a fun job, but it is something you can do. Check internet for instructions.. The important thing is to keep everything VERY clean. you do not want any dirt particles in you brake system. After rebuilding wheel cylinders, you will have to fill and bleed the system with new brake fluid. I hope this helps

25. ## How does viscosity of a fluid vary with temperature ?

In the word fluid there are two things one is liquid and second is gas. So if temperature is increase for liquid then viscosity is decreased and for gas it will be increased because fast movement of elements.
