Hi I feel I am competent enough at the Buckingham Pi theory regarding both Pipe flow and for Propeller analysis.
Derive a relationship between the volume flow rate and rotational speed of propeller in terms of the diameter of the pipe and propeller and also fluid characteristics density and...
What do "two-level" and "multi-level" gate circuits mean?
I have been doing questions relating to logic gates circuits, and have noticed that some questions say "implement with two-level NAND gate circuts"
And then a different question would say "implement with multi-level NOR gate...
An object weighs 30kg in air it is lowered into a square tank (1m x 1m)
the weight of the object in the water is 16kg. how much does the water level in the tank raise?
Heres my attempt.
30-16 = 14kg
14kg = 14 m^3
1 x 1 x h = 14
h = 14 metres.
Is this correct it doesn't seem...
Aspect ratio of cylinder floating in water?
Hi,
Basically the question is:
What is the aspect ratio (h/d) for a cylinder of specific gravity 0.65 above which it will float vertically? (Note use GM = I/V - BG)
So i found a solution that is simliar and can help solve the problem. (please...
Thats the problem i don't know how to check the answers by using two equations,
can anyone just tell me if either solution is correct or if they are both wrong?
Thanks

Which one of these solutions is correct?
1) V / R = I
6 / 1.5 = 4
i1 = 4a
3 / 2 = 1.5
i2 = 1.5a
i1 + i2 = i3
i3 = 5.5 amps
2)V / R = I
6 / 11.5 = 0.5217...

(1)P.d across coil = 2.pi.f. (0.32)
(2) P.d across capacitor = 2.pi.fr.(0.5 x 10^-6)
(3) P.d across resistor = 30v...
