Thanks for replying and i thought that was the case. Im having trouble with trying to derive an equation that will enable me to calculate the velocity or time for a compressed air from a tank trying to accelerate a projectile where the acceleration is not assumed to be constant. I already...

Im finding it really difficult to calculate the volume of a pressure vessel for my project. I have been only given values of pressure and temperature, where the pressure is 80psi and temperature is at room temp. Its difficult using the ideal gas law as i don't know the number of moles, nor i...

Is there an equation that relates the friction factor to the change in pressure or head loss for a closed channel flow - I am aware there exists equations that exits for open channel flow

Homework Statement Hey everyone I was wondering if you could help me - is there any known derivation for the volumetric flow rate through a fully developed turbulent channel flow, I've been looking for ages and can't find anything only for laminar flow. thanks in advance nar...

Hi all I was wondering if anyone could help me with calculating or finding the discharge coefficient for a fully developed turbulent flow through a vena contracta many thanks nar

Basically our task is to design a inclined manometer. with these parameters : the maximum pressure: 7875pa minimum pressure: -3200. what I am struggling on is calculating the angle that the manometer should be inclined at. Another parameter that is given is that the angle must be between 0-45...

Galileos idea of a fixed value for the gravitational acceleration on the Earth iss now accepted for most pratical calulations allthough variations in the Earth's crust mean that this value is not precisely uniform. However there is another phenomenon that will affected the decent of the cannon...
