Homework Statement In my notes it states that at a point in fluid, pressure act equally in all directions. While at a wall fluid act perpendicular at a wall. Why ? Homework Equations Pressure = force/area The Attempt at a Solution Can you please explain to me the reasons behind this

Thank you! One last question for the combined phasor. How should I be able to draw that? Would you please be able to attach simple exam on how to draw one? As I do not where to start.

LCKurtz You have confused me. Let's rewind back- I have drawn two images i) (http://imageshack.us/photo/my-images/3/plotb.jpg ii) The attached image Then you said " Your work looks OK, but I think your answer to (b) should be a picture of a phasor (which I don't see...

b)How should I draw a phasor? c) Again any help on what number ?

I have drawn two images. Also done a calculation. I was wondering if the images and calculation are correct?

Yeh (4,0°) and (3,27°) a)draw both phasors b)draw the combined phasor between (0 degree and 360 degree) c)label peak voltage and state its value

Homework Statement Two alternating currents are applied out of phase with each other. One is 4 volts and the other is 3 volts 27° out of phase. These can be written as (4, 0°) and (3, 27°) Homework Equations a)draw both phasors b)draw the combined phasor between (0 degree and 360...

Is my english really that difficult to understand? I have already completed the work just wanted some guidance on how this number came about.

Anyone! Just a small explanation will do

I did not know how to construct a formula. So I have attached the questions below and hopefully you will understand it better. Thanks

Homework Statement The following data has been collected: Gas volume: V = 0.8 m3 Gas pressure: p = 160 kPa Compression index: n = 1.4 Pressure/volume relationship: pV^n = C Work done = ∫ TOP=V2 BOTTOM =V1 You first need to work out C, the value of the pressure/volume relationship...

I have done my calculation and received r = 6.81v HOW SHOULD I label the peak voltage on the plot and state the value?

Thanks. I will try it and attached after my work

Thanks for explain but I have no idea. Sorry "(4^2 = P^2 + B^2)" May you explain where that came from
