		<description><![CDATA[How to Measure your Water Flow Rate Q from an Open Pipe: There are times when it&#8217;s necessary to estimate the flow rate from a stream constrained to flow in a water jet flowing from an open pipe. This flow measurement method doesn&#8217;t require us to have precision fluid flow measurement instrumentation, other than a [...]]]></description>

		<description><![CDATA[Hydropower penstocks or hydro system pipelines require attention to design regarding fluid flow and head loss. In this short review I'm letting you in on my secret, I use PipeFlow-Expert® by Daxesoft to make these initial penstock performance and energy loss design estimates.  It is a cycle of trial &#38; re-trial to find the sweet spot for a hydro site. A design spot  between power ROI and the sites infrastructure costs. These hydro capital costs include; electric switchgear, turbine and penstock costs, etc.  Hint - the penstock and associated hardware are often one of the most expensive components in a hydro system. ]]></description>

		<description><![CDATA[Hydrostatic head is the pressure rise caused by gravity acting on a column of water or fluid that is not in motion. In the case of a small hydropower system it comes from the difference in elevation between the intake of the hydro system penstock and downhill to the input side of the water turbine.
