GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I didn't pay attention much in physics class....<br /><br />Say I have a pump up sprayer, presurized to 10psi, is it spraying out the end at 10psi, or is it 10 X Square inches of surface area inside the sprayer?
The pressure is 10 psi throughout the sprayer including at the nozzle.<br /><br />The force exerted on the sprayer wall is the area X the pressure. (Pounds/square inch X square inches = pounds)
