Enzymes differ from most other catalysts by being much more specific. Enzyme activity can be affected by other molecules: inhibitors are molecules that decrease enzyme activity, and activators are molecules that increase activity.
This fact sheet briefly discusses several load estimation tech-. niques. Reasons to Determine Motor Loading. Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is. usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of. 5 to 10 hp; peak efficiency is at 7.5 hp. A motor âs efficiency tends to decrease dramatically below. about 50% load. However, the range of good efficiency varies with individual motors and tends to. extend over a broader range for larger motors, as shown in Figure 1.
Solar heating is the most efficient home heating system on all three criteria, and electric is the least efficient and least affordable. If you want to know why electric heating is so inefficient and expensive, or how to save on electric heating, see my Energy efficient electric heaters page.
