factors like altitude and air density. The speeds in ideal gases and air have their own formulas: Thus‚ For a gas the K is given by the formula above‚ and the C is the coefficient of stiffness in solids. Thus the second formula is given. (Gamma) is the adiabatic index‚ then is the pressure‚ and the regular P is the density. In general‚ the speed of sound is given in the formula: K is a coefficient of stiffness‚ the bulk modulus‚ and P is the density. Then there is a more complex

pneumatic system can convey a product at any place a pipe line can run. Pneumatic conveying can be used for particles ranging from fine powders to pellets and bulk densities of 16 to 3200 kg/m3 (1 to 200 lb/ft3). As a general rule‚ pneumatic conveying will work for particles up to 2 inches in diameter @ typical density. By "typical density" we mean that a 2 inch particle of a polymer resin can be moved via pneumatic conveying‚ but a 2 inch lead ball would not. Types of Pneumatic Conveying There are

According to the kinetic theory‚ both the particles in gases and the particles in liquids have kinetic energy. This energy allows the particles in gases and liquids to flow past one another‚ as shown in Figure 13.5. Substances that can flow are referred to as fluids. The ability of gases and liquids to flow allows them to conform to the shape of their containers. Figure 13.5 Both liquids and gases can flow. The liquid on the left is colored water. The gas on the right is bromine vapor. If a gas is

then the egg will float because the egg has a density that is lower that the density of the fluid it displaces. Background Information If the object has a density that is higher than the density of the fluid it displaces‚ it will sink. If the object has a density that is lower than the density of the fluid it displaces‚ it will float. Some objects that sink in fresh water will float in salt water. This is because saltwater has a higher density than freshwater. Websites that I used for this

Calculate the energy change (q) of the surroundings (water) using the enthalpy equation qwater = m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. The water has absorbed the heat of the metal. So‚ qwater = qmetal m=mass of water= density x volume = 1 x 26 = 26 grams ΔT = T(mix) – T(water) = 38.9 – 25.3 = 13.6 q(water) =26 x 13.6 x 4.18 q(water) = 1478 Joules 2. Using the formula qmetal = m × c × ΔT‚ calculate

application of rigorous optimization techniques to identify the critical subset of potential discontinuities‚ and hence also the critical failure mechanism and margin of safety. The accuracy of the DLO solution is controlled by the specified nodal density. Within the set of all possible discontinuitiues linking pairs of nodes‚ all potential translational failure mechanisms are considered‚ whether anticipated or not by the engineer. Failure mechanisms involving rotations along the edges of solid bodies

fuel tank‚ and a LV-T45 liquid fuel engine. After that we used three symmetry tool and placed radial decouplers as low as possible and placed AV-R8 winglets on it as low as possible as well. We used decouplers because we want it to detach on our way back and used winglets because it makes best landing‚ they are light‚ and they will not band or fall off. After that we added decoupler to the bottom of our rocket. Then we moved three radial decouplers one stage up and moved liquid engine one stage down
