Hi may i know if the pressure of air in the cylinder is acting upwards or downwards? I know the pressure of the cylinder is acting downwards and the pressure of water is acting upwards.
My teacher gave me this equation Pcyclinder= -(Pair + Pwater)
However i do not know why Pair is acting in the same direction as Pwater. I thought Pair should be acting downwards, acting on the water instead?
Can someone help me with this? Thanks
