For example, a 300-hp hydraulic system is assigned an efficiency rating of 70% or 210 hp. The remaining 30%, 90 hp, is lost as heat. The 90 hp converts to 3,820 BTU/min or 229,200 BTU/hr, or 67.14 kW. After the system is built, heat rejection is determined by measuring the fluid temperature rise during system operation over a period of time.Effective Layouts | Superior Radiant ProductsEquipment efficiency factors for low intensity, where some systems can achieve thermal efficiencies of in the low 80% range, can rise to 15% and 20%. Over sizing a radiant heating system rarely adversely affects the equipment itself, but the more frequent cycling of an oversized system will decrease personal comfort and fuel economy.Choosing Between Hose and Tube Assembly for Hydraulic When sizing components for hydraulic systems, it is the ID dimension that is important to determine the flow diameter, flow velocity etc. So when you are considering which will be lighter in your application, you should compare tubes and hoses with the same diameter and required pressure rating instead of using nominal size.
With enough hoses used in a system, the increase in the amount of hydraulic fluid necessary to complete the task can become noticeable and may need to be considered in the design stage. In addition, the hoses volume fluctuation decreases the hydraulic system reaction time and efficiency.Chapter 6 Irrigation System Design - USDAsystem.
