gravity, radius, pressure and length?

if we say resistance then it should be increased with a longer length of a pipe (R=8nL/piR^4) but here the results are showing that the flow is faster with a longer pipe

Please explain why flow down a vertical pipe would be slower if the length is shorter

I have repeated the experiment several times and it always shows my longer length has the fastest flow rate. the same results occur when I apply 300mmH pressure to the fluid bag on top, the flow rate is still faster in the longer pipe

why would the column of water differ, they will both contain the same amount, as they are both 100cm length except one is coiled in the middle so that the new measured length from its inlet to outlet is 30cm

I'm studying fluid dynamics. do you believe coiling would lead to slower flow rate

there is an experiment I have to design to test the difference in flow rate in a tube of 3mm internal diameter of 100cm length where initial pressure is 300mmHg the second pipe I would coil over a 10cm diameter cylinder shortening the initial length from 100cm to 30cm. all other properties kept...

the straight and coiled pipe are vertical with the coiled pipe wound around a vertical cylinder

so in this case coiling it would result in higher head loss and slower velocity at the same exerted pressures?

the straight and coiled pipe are vertical with the coiled pipe wound around a vertical cylinder. the 2 pipes when straight are of equal length but the coiled pipe appears shorter due to being wound around the vertical cylinder

If you have 2 pipes of the same cross sectional area, same volume of fluid, and same length, the only difference is one pipe is coiled several times over a cylindrical object theoretically shortening the length of the pipe, while the other is a straight pipe. Will the flow rate be same in both...
