Homework Statement How far will water shoot from a hole in a pipe knowing the pipe pressure, hole size, and exit liquid velocity and flow rate. It is assumed that the hole is located such that the water is sprayed at a 45 deg angle from the horizontal. Homework Equations Basic projectile...

Hey thanks for the reply, yeah that's what I thought. I forgot to mention that I have hot air flowing through the water which would be the cause of evaporation.

Hi all, I have a (probably very simple) problem that I need some help with. If I have a body of water in which the temperature of the water, ambient air temperature and mass of the water is known; how do I calculate the rate of heat loss from the water? Using Q=m*cp*(Twater-Tair) I can find out...

Thanks, I think I have that part figured out. The compressor I will be using has a maximum working pressure of 7.5 bar, will a flow meter with a max pressure rating of 6.9 bar be ok or should I look for a higher one? Edit: I assume that I would just be able to adjust the working pressure of...

Hi all, Currently I am undertaking a project and I am a little bit confused about the free air delivery (F.A.D.) of an air compressor because I need to purchase an air flow meter and don't want to buy something completely out of the ball park. From the information sheet, the compressor has...

Hey i got the answer (sin4x)/32 + (sin2x)/4 + (3x)/8 + C which seems to be right. Thanks for your help :)

Homework Statement Find the integral of cos4 xdxHomework Equations cos2x = 2cos2x-1 cos2x = (cos2x+1)/2The Attempt at a Solution I tried using cos4x = cos2x * cos2x and i simplified it to cos4x = ((cos2x)2 + 2cos2x + 1)/4 I'm not sure if this is right. How do i go about getting the integral...
