Likewise, the cone-cylinder join at small diameter side, affected by internal pressure, must withstands, usually, tension effect. Nevertheless, if internal pressure is exchanged for external, the large end side will be affected, generally, by a tension effect while the small end side, by one of compression.

Supersonic Flow Past a Cone

May 13, 2021· There is a loss of total pressure associated with a shock wave. On this web page, we show a method for determining the supersonic flow past a cone. The method was first developed by G.I. Taylor and J.W. Maccoll in 1933. The derivation of the differential equation shown on the slide is fairly complicated.

acoustics - Relationship between sound pressure level and ...

This means that the pressure is proportional to the cone acceleration. So, in terms of the cone displacement, we have $$ p = -frac{rho S_D}{2 pi r},omega^2 x $$ I believe that this answers the OP's question. It means that the pressure produced by the cone is proportional to the displacement times the square of the frequency. Finally, we ...

Piezometer Ring Airflow Measuring System

The inlet cone of the fan is used as the flow nozzle and the flow can be calculated by measuring the static pressure drop through the inlet cone. The pressure drop is measured from the tap located on the face of the inlet cone to the piezometer ring in the throat. The inlet tap is connected to the high-pressure

V Cone Flow Meter Working Principle - InstrumentationTools

The V-Cone flow meter like several other popular meters is a differential pressure (or "DP") meter. These meters all work according to the same principle of DP flow devices. That is an obstruction in the pipe (i.e., a reduction in the cross sectional area available to the flow) causes an increase in flow velocity and a corresponding reduction in pressure.
