Experimental Investigation Of Various Minor Losses By Using Bourdon Pressure Gauge

Abstract

The Term “minor Losses”, Used In Many Textbooks For Head Loss Across Fittings, Can Be Misleading Since These Losses Can Be A Large Fraction Of The Total Loss In A Pipe System. In Fact, In A Pipe System With Many Fittings And Valves, The Minor Losses Can Be Greater Than The Major (friction) Losses. Thus, An Accurate K Value For All Fittings And Valves In A Pipe System Is Necessary To Predict The Actual Head Loss Across The Pipe System. K Values Assist Engineers In Totaling All Of The Minor Losses By Multiplying The Sum Of The K Values By The Velocity Head To Quickly Determine The Total Head Loss Due To All Fittings. Knowing The K Value For Each Fitting Enables Engineers To Use The Proper Fitting When Designing An Efficient Piping System That Can Minimize The Head Loss And Maximize The Flow Rate. The Objective Of This Experiment Is To Determine The Loss Coefficient (K) For A Range Of Pipe Fittings, Including Several Bends, A Contraction, An Enlargement, And Agate Valve. In Our Capstone Project Work Our Main Objective Is To Replace The Manometer Which Is Available In The Experimental Set Up By Pressure Gauges For The Accurate Reading And Further Calculations. So That The Effectiveness And Reliability In The Performance Of The Test Ring Must Be Improved In Comparison With The Manometer.
