That would put us into compressible flow. If the OP only needs the volumetric flow rate at the nozzle (ignoring gas density), the equation should work fine. But if he needs to know how much gas actually passes (scfm or mass flow rate), he needs to consider the density change of the gas, which...
Why would you assume the gas velocity is mach 1? The velocity is dependent on the flow rate and size of the orifice. And that is dependent on the pressure differential driving the gas through the orifice. You might try calculating this like an orifice plate in a pipe.
I'd say its possible it may leak more, but it could just as easily leak less if you looked at the other connection in your diagram. Its not a simple question you are asking. There are a number of variables that can affect this, including flow rate, piping wall thickness, pipe diameter, shape...
The biggest hurdle at this particular moment is actually oil prices being so low. There was a lot more demand for it in the commercial truck space even as late as last year before the huge drop in oil prices. Infrastructure is growing, and it can be reasonably practical to have a CNG powered...
This. The geometry may cause a local high or low pressure area next to the leak. And this could change at different flow/pressure levels. I test with a lot of high pressure gas systems at work. I recall one incident where I was emptying a cylinder from about 5K psi and it emptied through the...
Find a rigid object in your house that has a "T" shape to it. A T-Handle tool might be a quick find if you have one (If you don't, just try and follow this conceptually). Grab the object by the leg of the "T" and spin it along the axis of the leg. The top of the "T" will twist. This is...
I agree on the slope aspect, but I think relating it to Kinetic Energy is incorrect. Consider F=ma. If you removed friction and aerodynamic resistance, a given magnitude of force will accelerate the mass by the same amount regardless of the initial speed. That is, if you applied the same...
It was explained, but not clearly pointed out. The rotational motion of the motor and driveshaft is easy enough to understand. Why one side of the car jacks up is because as the tires grip the road under the load, the mass of the car resists the force provided by the motor. Since there is a...
Gears was already mentioned, but just as important, high RPM operation. As I mentioned before, high engine RPM acts as a longer lever arm. So you can take a small amount of force and do a lot of work. As I mentioned before:
HP = (Torque x RPM)/5252
And one way to apply HP is by applying...
In general, I'd say engineering majors do take longer as there are more prereqs needed before you can take the needed courses for transfer in your intended major. This can probably be said of most science related majors though. I think the only big prereqs for humanities are for English if one...
You don't necessarily have to decide before the deadline. First of all, you are merely applying and unless you have signed up for and qualify for a transfer guarantee program, you still have to be accepted. Best course of action is to apply to all the schools you are considering seriously and...
I can't imagine you couldn't find an EE program and physics courses at any 4 year uni. The questions should be quality of program, cost of attendance (include dorm or apartment expenses if you can't commute and commuting expenses if you can). Also consider your path. If you are planning to...
Its easy to get confused about this as more torque should net more acceleration (at that instant). And in fact, this is actually true in any given gear. If you measure instantaneous acceleration in every gear, the fastest acceleration in each gear will occur at the torque peak. Where this...
