    Why does it take more energy to heat nitrogen?

    Well...that's a good question. Nitrogen is typically used in these units, which I assumed was because it ran cooler than air, and for the fact that it was free of moisture. The units typically have a rubber bladder that isolates the gas from the fluid. This bladder is charged to 130 to...

    Why does it take more energy to heat nitrogen?

    It was the same unit. We just let it sit for a few hours between tests.

    Why does it take more energy to heat nitrogen?

    So we tried two methods, one was via an enclosed oven, the other was via a heat gun. The units have about 450ml of fluid/oil in them and about 200ml of a gas chamber (that remains isolated from the fluid) which is charged at about 150PSI. As the main bodies of the damper are aluminum, the...

    Why does it take more energy to heat nitrogen?

    I guess this might have something to do with it.

    Why does it take more energy to heat nitrogen?

    Ah...thanks. So all factors are equal, and whatever it is, it makes a big difference as it takes a significant amount more heat to bring the nitrogen filled unit up to a given temp than the unit filled with regular "air". In other words, I'm not talking about small amounts...it's a very...

    Why does it take more energy to heat nitrogen?

    Hey guys, If this is in the wrong section let me know and I'll move it. So here's the simple question. I work in an industry in which we pressurize fluid based dampers with nitrogen. Those units pressurized with nitrogen take more energy to heat up than those pressurized with ambient...

    Calculating Force of Jumping Motorcycle

    Thanks! So what if we simplify this by saying that we are rolling a bowling ball at a given speed, at a ramp that is 2 feet long and one feet high? Can we calculate how much force the ball will hit the ground (landing) with? And then what happen if the ramp is curved instead of being flat?

    Calculating Force of Jumping Motorcycle

    Ah...good stuff and thanks for the info. So...just to make sure that I have this correct, for as elementary as it may seem, if we have a ball that is 10 kilograms in weight (the mass) and we drop it any distance (assuming is can reach its maximum velocity) the force of the impact is 98 kgf?

    Calculating Force of Jumping Motorcycle

    Hey guys, New to the forum but full of so many questions, of which I assume will be a cakewalk for many of you. I'm no physics expert as you will soon discover. Looking foward to your input and assistance. The first question is how do I calculate the force associated with a falling...
