Where the cold fluid velocity (Vc) = 1.19 m / s can absorb heat until the temperature of the cold fluid rises to 44.7вњ¬ and until the speed (Vc) = 2.91 m / s the increase in temperature of cold fluid is only up to 41.6вњ¬ because the shorter contact time makes the heat absorption of the hot fluid shorter, then if the speed of the cold fluid is increased continuously it will make the absorption of heat from the hot fluid go down which results results in the effectiveness of the heat exchanger going down.ДЄfandi, Nurlan. but this increase in effectiveness does not go on where it will reach a point where the effectiveness does not increase but decreases. Where is obtained the most optimal characteristics at cold fluid velocity (Vc) = 2.91 m / s and minimum cold fluid velocity (Vc) = 1.19 m / s, it is found that increasing the speed of cold fluid flow can increase the performance or effectiveness of a device heat exchanger. Characteristics of heat exchangers include Reynold numbers (Re), Nusselt numbers (Nu), convection coefficients (h), overall convection coefficients (U), heat transfer (q), and effectiveness (Оµ). From the results of the study obtained the characteristics of a heat exchanger increases with the increase in the speed of cold fluid. This test is performed by forced convection by varying the speed of the cold fluid (Vc) which is 1.19 m / s to 2.91 m / s with a constant hot fluid velocity (Vh) = 1.98 m / s at the temperature of the incoming hot fluid ( Th, 1) = 60вњ¬ and cold fluid temperature (Tc, 1) = 32вњ¬ which is made constant.

Theoretically the increase in flow velocity will increase the value of effectiveness and can enlarge the Reynold numbers and Nusselt numbers which then increase the heat transfer by covection. The 10th Edition introduces numerous changes to the TEMA Standards, including: NEWLY ADDED: Numerical Analysis of Expansion Joints (1-Dimensional FEA) Comprehensive Rules for the Design of Horizontal Saddle Supports Dimensional Data for Flanges Guidelines and Configuration of Distributor Belts Fouling Mitigation Design Study Guidelines for Expanded Tube to Tubesheet Joints Sketches of Collar Studs for Removable Bundles Incorporates ASME PCC-1 Recommendations for Bolted Joints UPDATED: Updated International Material Chart Updated Metric Bolting Data Chart Updated Graphics and Charts to a Modernized and Standardized Format and Appearance As the industry has changed, so has the TEMA Standards book. Since the founding of the Tubular Exchanger Manufacturers Association in 1939, the TEMA Standards have been specified by industrial plants worldwide.
