For example, a heavy grade steel 15mm pipe @ 80&deg;C and a flow rate 0.062kg/s is showing a pressure drop of 387, would expect it to be&nbsp;much lower than this.&nbsp;<br /><br />Please can you advise?<br /><br />thanks&nbsp;</p> <p>Simon</p> <p></p><div style="clear:both;"></div>Ask A Question Ihttps://communities.bentley.com/achievements/460ac7df-7ccc-4c42-a204-9e05eef3be09Thu, 12 May 2022 01:03:55 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:78ea1f6c-f0c5-409e-84e3-8510c507442aAsk a question in a forum.
