differential pressure______
举一反三
- Which of these is the most complete list of the agents of metamorphism, the agents that drive metamorphic transformations in rocks? A: pressure, temperature, heat B: chemically active fluids, pressure, differential stress C: heat, differential stress, chemically active fluids D: heat, pressure, parent rock
- A differential connection cylinder circuit,（ ）of the cylinder increase。 A: force B: pressure C: speed D: flow rate
- 词汇与结构 If the cabin were ______ at sea level pressure while flown above 35,000 feet the pressure differential would exceed 9 psi limiting the structural life of the fuselage.
- According to the different causes, gap flow can be divided into three types: differential pressure flow, shear flow and ( ) flow.
- In order to ensure that the pressure difference between the front and rear of the throttle valve remains unchanged when the load changes, the flow through the throttle valve is basically unchanged. The throttle valve is often connected with ( ) to form a speed control valve, or the throttle valve and ( ) are connected in parallel to form a bypass speed control valve. A: Pressure reducing valve B: constant pressure reducing valve C: overflow valve D: differential pressure relief valve
