A speaker driver can be modeled as a one degree of freedom forced system with damping. The mass of the moving cone is m=0.1 kg and the spring k=50000N/m. The electromagnetic force of the coil produces a forcing function F=100Ncos(\omega t), plot the magnitude X and phase \theta of the vibration of the cone as function of the forcing frequency f in cycles per second for damping coefficients \zeta=.5, 1., 5.

What is the convective heat transfer : A square vertical plate measuring 0.25 m on each side is exposed on one side to air at 1 atm and 10 C. If the plate is held at a constant 286 C, what is the convective heat transfer?
Find the convective heat transfer in the channel : Two plates are suspended vertically in 20 C atmospheric air forming a channel of width 18cm. The plates are 3m high and are maintained at a temperature of 275 C. If the channel is 5 m deep, find the convective heat transfer in the channel
Rate of heat transfer between the steam and cooling water : A shell-and-tube heat exchanger is used to cool a flow of steam using a stream of cooling water. The steam enters the heat exchanger at 0.1 bar and a quality of 91% (state 1), and exits as a saturated liquid at the same pressure (state 2).
