What happens if you inhale mercury from a light bulb? Mercury in CFLs are present as elemental (or metallic) mercury. Once inhaled, the mercury vapor can damage the central nervous system, kidneys, and liver. These toxic effects are why any mercury spill should be handled carefully, including one that results from a CFL breaking. Do […]
What is the same in all parts of a series circuit?
What is the PMV?
What is the PMV? The predicted mean vote (PMV) was developed by Povl Ole Fanger at Kansas State University and the Technical University of Denmark as an empirical fit to the human sensation of thermal comfort. It predicts the average vote of a large group of people on the a seven-point thermal sensation scale where: […]
What happens when a thermostat gets too hot?
What happens when a thermostat gets too hot? As the thermostat opens and coolant starts flowing through the radiator, the temperature of the lower radiator rises quickly close to the temperature of the upper hose. If a thermostat is stuck closed, the engine might overheat, which can result in expensive repairs. What are signs of […]
How does pressure affect distillation?
How does pressure affect distillation? the authors state that increasing pressure can decrease the diameter of a distillation column for a given separation. For example, Winkle (1967) noted that ”vapour volume increases as pressure decreases, and larger diameter columns are required to handle the increase in vapour volume. How do you calculate reflux ratio in […]
Can an insurance company not renew my policy?
Can an insurance company not renew my policy? In California, insurance companies must give homeowners at least 60 days’ notice if they plan to non-renew a policy. And regardless of state, insurance companies can non-renew a policy for a number of reasons, including these: They no longer offer the coverage you were paying for. What […]
What is the opposition to the flow of current?
What is the opposition to the flow of current? electrical resistance: The opposition offered by an electrical conductor to the flow of a current through itself, resulting in a conversion of electrical energy into heat and radiation. The SI derived unit of resistance is the ohm. Is resistance the opposition to current flow? Resistance is […]
What do you have to be good at to be a biomedical engineer?
What do you have to be good at to be a biomedical engineer? Students interested in becoming biomedical engineers should take high school science courses, such as chemistry, physics, and biology. They should also take math courses, including algebra, geometry, trigonometry, and calculus. Courses in drafting or mechanical drawing and in computer programming are also […]

How is thermal comfort measured?
How is thermal comfort measured? Thermal comfort is generally thought to be captured by measurements of four quantities: dry-bulb temperature, relative humidity, air speed, and radiant temperature. This heat pump uses small diameter flexible ducts, with a blower that allows for air to be injected into rooms at higher speeds. What is thermal comfort index? […]
