For an infiltration rate of 1.08 air changes per hour (ach), determine sensible, latent, and total infiltration heat load of a building at sea level, in kw, that is 20 m long, 13 m wide, and 3 m high when the outdoor air is at 38 degree c and 35 percent relative humidity. the building is maintained at 24 degree c and 55 percent relative humidity at all times. q_infiltration, sensible = q_infiltration, latent = kw q_infiltration, total = kw

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.
