The usual configuration for a converging diverging (CD) nozzle is shown in the figure. Gas flows through the nozzle from a region of high pressure (usually referred to as the chamber) to one of low pressure (referred to as the ambient or tank). The chamber is usually big enough so that any flow velocities here are negligible. cuban bakery hillsborough ave tampa flWeb6.1 Modeling Sound Transmission. Air has mass, and it also acts as a spring--it can be compressed by applying force. Like any mass-and-spring system, it is able to store and transmit energy in the form of vibrations. In the particular case of air, these vibrations move in waves from one place to another. cuban bakery estero fl
