I'm doing a similar experiment, and have my theoretical values coming off around 7, even though my actual values are around 1.6... I'm not entirely sure but isn't the force equal no matter how far away the jet is due to conservation of momentum: even though the speed of the jet may not be as...

Ah, good point, well yeah. Guess it isn't then. I meant more that I don't know if we're supposed to be including whether the air jet slows down due to the other air particles in the room...It isn't mentioned so I assumed not.

Air resistance is neglected. Well I have values of 10.104 - 10.202 for the practical measurements and 7.167 for the theoretical value. I think the calculations are all right, but will go over the numbers again to check

I know this is from a while back, but still: if anyone gets this: I'm doing a similar problem at the moment, but I also have real values measured in the Lab, is it likely the theoretical values would be higher or lower than the actual values? Just want to check I'm on the right lines before I...
