11. It employs variable timing, which adjusts the exhaust valves depending on speed and load conditions . 12. When combined with superposition, symmetry and anti-symmetry, it can be used to resolve complex load conditions . 13. This spillover under low-load conditions is seen as automatic and inevitable, thus not under voluntary control. 14. It is well known that operating engine-generators under fluctuating load conditions can present a number of problems. 15. Practical thermal efficiency of a steam turbine varies with turbine size, load condition , gap losses and friction losses. 16. They are dynamic, deliver value in real time, and can react quickly to changing customer load conditions ." 17. Similarly, the test load conditions of MFI measurement is normally expressed in kilograms rather than any other units. 18. The poles are designed to address a wide range of strength, height and load conditions and technical standards. 19. Because VAV air flow is reduced under part-load conditions , air is exposed to cooling coils for a longer time. 20. These type of appliances are typically designed for specific re-load conditions meaning that they generally have a larger cooling system.
