Question

True-False

6) In permanent (steady) flow, the instantaneous average of pressure values at a certain point is constant, as long as the number of sampling or measurement time is sufficiently long. 7) A permanent flow is always a uniform flow. 8) An unsteady flow cannot be producible in a pressurized pipe, which has a constant diameter along the flow. 9) The flow around a riverine stone in a natural stream is a typical example to two-dimensional flow. 10) Whilst pressure is a scalar magnitude, hydrostatic force is vectoral.
