Experimental methods
1.Turn on hydraulic bench pump. Next open valve for enter water in the cylinder glass with appropriate velocity. and measurs flow rate from the water flows out. After than measure the volume of water per times until the water in the cylinder glass constant.
2.Open valve from the cone with the water color to release the water color flowing into the glass tube. Notice the colors flow from the top to bottom in various aspects and record. If the color line explode within a glass tube, then Reduce the flow rate of water and dial valve for Enter the water just enough in the cylinder glass at constant height. The flow rate to make line color is laminar flow
3.Gradually add the flow rate by opening a effluent valve until the color mixed. This is condition to call the transition a position to change from laminar flow to the turbulence flow .If add the flow rate of water to the cylinder glass. By maintaining the height of water in the cylinder glass to constant. Flow will change to the turbulence flow
4.Measure the temperature of water by thermometer and measure flow rate of water by volume of the water flows out. From glass tube and timer
5.Reduce the flow rate down gradually until the color mix full glass tube change to small line color at constant flow rate again
