Question:
mam in 20th part you said that p1>p2.from fig A1>A2.we know p=F/A.so, P should be inversely proportional to A.then p1
Answer:
The 20th video part on Mechanical properties of fluids deals with the explanation and working of Venturimeter. It is the device to measure the flow speed of incompressible fluid.
However, the video says A1 > A2 Hence, P1 < P2 as pressure is inversely proportional to the area of cross-section. Also please find attached the screen shot from the video for quick reference.
