Answer / naveed iqbal butt

inlet of the primary flow element is called upstream where
pressure increase and volicity decrease,outlet of the
primary flow element is called down stream where volicity

Answer / ahmed helmy

upstream means high pressure
downstream means low pressure
in liquid flow, the flow is directed in pipe from high pressure to low pressure

Answer / carl_ellis

Upstream is a higher pressure than downstream and
downstream is lower pressure than upstream, because it is a
difference in pressure that causes a liquid to flow.
