Webconsidered a future task. As such, the present model assumes isentropic flow of a perfect gas through the inlet. The CFD model does have a sub-model for calculating losses in the inlet, and for the two operating points examined, it predicts an inlet total pressure loss of approx imately 50%. When the pres ent lumped volume model was In fluid dynamics, dynamic pressure (denoted by q or Q and sometimes called velocity pressure) is the quantity defined by: where (in SI units): • q is the dynamic pressure in pascals (i.e., kg/m/s ), • ρ is the fluid mass density (e.g. in kg/m ), and

Webshaft gas turbine is shown in Figure 3. The low-pressure or power turbine rotor is mechani-cally separate from the high-pressure turbine and compressor rotor. The low pressure rotor is said to be aerodynamically coupled. This unique feature allows the power turbine to be operated at a range of speeds and makes two- WebJan 7, 2003 · pneumatic load. The high-pressure inlet gas creates a pneumatic force (F i) pushing on the face of the valve seat forcing open the valve. An adjustable spring force (F s) assists the high inlet pressure by pushing on the sensing device (diaphragm), opening the valve to maintain the set pressure. These forces can be calculated as follows: (Hooke ... fnf toggles script
