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? […]
What are other skills that enhance communication?
What are other skills that enhance communication? There are specific things to do that can improve your communication skills: Listen, listen, and listen. Who you are talking to matters. Body language matters. Check your message before you hit send. Be brief, yet specific. Write things down. Sometimes it’s better to pick up the phone. Think […]
Is J kg the same as M s?
How far can you travel on a full tank of gas?
Which radiation law describes the type of radiation an object will emit?
Which radiation law describes the type of radiation an object will emit? Planck’s Law Of course, the sun is a big nuclear furnace, so it makes sense that it emits all sorts of electromagnetic radiation. However, Planck’s Law states that every object emits over the entire electromagnetic spectrum. That means that you emit radiation at […]
What are two reasons for installing blocking or bridging between floor joists?
What are two reasons for installing blocking or bridging between floor joists? Floor joist bridging is critical to the structural strength of a floor, as shown in Figure 1. Proper bridging distributes the load on the floor to other joists and over time prevents floors from sagging and squeaking do to floor joists twisting and […]
What affects engine efficiency?
What affects engine efficiency? The efficiency of internal combustion engines depends on several factors, the most important of which is the expansion ratio. For any heat engine the work which can be extracted from it is proportional to the difference between the starting pressure and the ending pressure during the expansion phase. Why are 2 […]
Does adding heat increase entropy?
Does adding heat increase entropy? Affecting Entropy If you increase temperature, you increase entropy. (1) More energy put into a system excites the molecules and the amount of random activity. (2) As a gas expands in a system, entropy increases. This one is also easy to visualize. What happens to a system as entropy increases? […]

How do you cut across the grain?
How do you cut across the grain? Here’s Why It’s Important to Slice Meat Against the Grain First, find the direction of the grain (which way the muscle fibers are aligned), then slice across the grain rather than parallel with it. In the photo above, you can see that the muscle fibers run from left […]
