1. The problem statement, all variables and given/known data The pressure difference between the main pipeline and the throat of a venturri meter is 10.5 Pascals (Pa). The areas of the pipe and the constriction are 0.1 m^2 and 0.05 m^2 respectively. How many cubic meters per second are flowing in the pipe? The liquid in the pipe is water. 2. Relevant equations [itex]Q = A_1 V_1 = A_2 V_2 [/itex] where a = area v = velocity 3. The attempt at a solution I don't know if I should put 15 Pa on Q, so my solution goes like this: [itex]10.5 = (0.1) V_1 = (0.05) V_2 [/itex] I don't know what the next steps are, and by the way I tried to look for the forces using F = PA, which I got F1 = 1.05 N and F2 = 0.525 N. But I still don't know yet how to continue solving it. Any suggestions or solutions if available?
