What is the formula for calculating principal payment? What Is Your Principal Payment? The principal is the amount of money you borrow when you originally take out your home loan. To calculate your principal, simply subtract your down payment from your home’s final selling price. For example, let’s say that you buy a home for […]
How are conductor sizes expressed?
How are conductor sizes expressed? Conductor sizes are expressed in American Wire Gage (AWG) or in circular mils. Conductor sizes found in Chapter 9, Table 8 of the National Electrical Code® start with 18 AWG (the smallest size) and end up at 2000 circular mils (the largest size). How is wire diameter expressed in the […]
How does fouling factor affect heat transfer?
How does fouling factor affect heat transfer? The deposition of any undesired material on heat transfer surfaces is called fouling. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers. Fouling also impedes fluid flow, accelerates corrosion and increases pressure drop across heat exchangers. What are the common causes […]
Can a tight serpentine belt cause loss of power?
Can a tight serpentine belt cause loss of power? If the belts are too tight, they can put a strain on the shaft (and its bearing) of the alternator, power-steering pump and even the water pump. How long does a serpentine belt usually last? 60,000 to 100,000 miles What happens if serpentine belt breaks while […]
What is the purpose of the Reynolds Transport Theorem?
What is the purpose of the Reynolds Transport Theorem? Reynolds transport theorem (RTT) expresses the relationship between the rate of change of extensive property of a system and for the control volume. The main purpose of the RTT is to provide the link between the system and control volume. What is the relationship between the […]

What does a negative reading on a voltmeter mean?
What does a negative reading on a voltmeter mean? If they are switched, there will be a negative voltage. If the poles of your voltmeter are correctly connected, there is a possibility that the battery suffered a phenomenon called “polarity reversal”. This is a rare phenomenon that can happen at the end of a discharge […]

What are the movements of an airplane?
What are the movements of an airplane? There are three types of movement of an aircraft: pitch, yaw, and roll. Roll is controlled by the ailerons and rotates the airplane. Yaw turns the airplane and is controlled by the rudder. Finally, pitch is controlled by the elevator and changes the altitude of the airplane. What […]
