A mechanical pressure release valve opens at pre designed pressure and then automatically closes once pressure drops to a lower point generally around 5 to 10% of the designed release pressure.
However I need a mechanical pressure release valve which opens automatically at pre designed pressure...
Thanks a lot for your feedback Simon and Sophie. My one way mirror analogy was not correct I guess...
@Sophie: By opaque I meant that the surface should scatter light in all the directions so that when I look at that surface all I see is a white surface-Something like a sand blasted glass or...
Hi,
Is there any optical sheet or film which is transparent to object only if the object is touching or extremely near to the sheet otherwise it acts as opaque sheet?
For example, If we look through a transparent glass window of an apartment, from a distance in day light, we can’t see what or...
Is there any way to design a lens or system of lenses where I see the same part of the image, irrespective of direction or angle of view. The light rays can be assumed to be collimated as viewing will be from a distance.
Actually- I am looking at focusing on a point or specific area of the...
Thanks...So if charged capacitor is source of static electricity, can it move the pith ball or attract small bits of paper like a charged balloon or charged comb does? is it possible to build a electrostatic levitator based on parallel plate capacitor?
Suppose I first charge a capacitor so that one plate is positively charged and another negatively. Now I remove the charging source and ground only one of the terminals say negative terminal, will there be a net positive charge in the capacitor that can be detected by a pith ball?
Can a...
