MOTOR TEMPERATURE RATINGS A frequently misunderstood subject related to electric motors is insulation class and temperature ratings. This paper tries to describe‚ in basic terms‚ the temperature relationships that are meaningful in standard AC induction motors. Some of the same information can be applied to DC motors but DC motors are more specialized and some of the ratings are slightly different. Perhaps the best way to start is to define the commonly used terms. MOTOR SURFACE TEMPERATURES

huge amounts of energy‚ and their molecules are spread out as much as possible. With very little pressure‚ when compared to liquids and solids‚ those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want‚ and the gas escapes

Measuring the efficiency of various carbohydrate substrates in yeast fermentation. Cherrishe Brown October 3‚ 2007 Dieldrich Bermudez BSC 2010L Sect# 0560 Discussion As expected in the experiment Glucose‚ Fructose‚ and Sucrose were all utilized for fermentation. Based on the rate of evolution of CO2 the yeast was most efficiently able to utilize the substrate Glucose‚ followed by Sucrose and Fructose respectively. Given more time I believe that Sucrose would have surpassed glucose in total

of reactions that converts glucose to pyruvate with the concomitant formation of ATP. Three fates of this pyruvate produced exist. In this practical the production of pyruvate and acetaldehyde by fermentation of glucose is established. A series of test tubes was set up each containing glucose and yeast suspension in buffers at different pH values. These test tubes were incubated for an hour at 37℃. Trichloro-acetic acid solution was then added to the first 2 of the 4 test tubes prior to centrifugation

Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHCO3) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHCO3 increases the rate of photosynthesis of the Cobomba plant should increase‚ as there is a greater presence of a carbon dioxide‚ obtained

Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder
