Buckingham Pi Theory: Propeller & Pipe Flow Analysis for Jay
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...- jayjay112

Logic gate circuits - What does two-level and multi-level mean?
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...- jayjay112

How Much Does the Water Level Rise with a Submerged Object?
1000 kg/m^3 = rho so W/1000 x 9.81 = h? =14000/9810 = 1.43m? Thanks for the help- jayjay112

How Much Does the Water Level Rise with a Submerged Object?
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...- jayjay112

Aspect ratio of cylinder floating in water?
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...- jayjay112
