Propane (c3h8) burns completely with 230% of theoretical air entering at 74°f, 1 atm, 50% relative humidity. the dry air component can be modeled as 21% o2 and 79% n2 on a molar basis. the combustion products leave at 1 atm. determine the dew point temperature of the products, in °f. (there is a ±5% tolerance)

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
