    Calculating Rate of Heat Loss from Water

    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...

    Air Compressor Free Air Delivery question

    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...

    How to Integrate cos4 x Using the Double Angle Formula

    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...
