How do you calculate heat loss through a wall? Heat loss from the walls: Area of the walls = 1,920 ft2, HDD = 6,100, and the composite R- value of the wall needs to be calculated. Total heat loss from the house = 13.78 + 84.91 + 18.30 =116.99 MMBTU in a year or heating […]
For what values of k is the system stable?
For what values of k is the system stable? If K < 1386, the system will remain stable. If K > 1386, the system will remain unstable. How do you determine a closed loop stability? The determination of stability is based on the closed-loop characteristic polynomial: Δ(s,K)=1+KGH(s). What are the characteristics of stable and unstable […]

What must be added to the polynomial f/x )= x 4 2×3 − 2×2 X − 1 so that the resulting polynomial is exactly divisible by x2 2x − 3 )?
How do you calculate V peak to peak?
What effect does the wind chill factor have on temperature?
What effect does the wind chill factor have on temperature? The wind chill factor describes what happens to a body when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body […]
How do you prevent hydroplaning?
How do you prevent hydroplaning? How do I Avoid Hydroplaning? Keep your tires properly inflated. Rotate and replace tires when necessary. Slow down when roads are wet: the faster you drive, the harder it is for your tires to scatter the water. Stay away from puddles and standing water. Avoid driving in outer lanes where […]

What is the steady-state response of a system?
What is the steady-state response of a system? A steady-state response is the behavior of a circuit after a long time when steady conditions have been reached after an external excitation. What is sinusoidal response? The sinusoidal response of a system refers to its response to a sinusoidal input: u(t)=cosω0t or u(t)=sinω0t. To characterize the […]
What metal is used for turbine blades?
What metal is used for turbine blades? Nickel alloys What is the hottest part of a turbine engine? The engine exterior and the engine nacelle are cooled by passing fan air around the engine and the nacelle. The engine compartment frequently is divided into two sections. The forward section is referred to as the cold […]
