What do solar energy systems engineers do? Solar energy systems engineers work to improve the energy efficiency of residential, commercial, and industrial buildings using solar energy systems. These engineers perform site-specific engineering analysis or evaluation of energy efficiency for their customers. What type of engineers work with solar power? Solar energy engineers, also known as […]

What is the principle of precipitation hardening? Age hardening, also known as precipitation hardening, is a type of heat treatment that is used to impart strength to metals and their alloys. It is called precipitation hardening as it makes use of solid impurities or precipitates for the strengthening process. What is precipitation hardening of Aluminium? […]

How do you find the shear angle of an aircraft? In a chip formation process, the shear plane angle is the angle between the horizontal plane and the shear plane. It is calculated by this equation: Tan angle is equal to chip ratio cosine rake angle divided by 1 minus chip ratio sine rake angle. […]

What type of network uses the CSMA CD access method? Carrier-sense multiple access with collision detection (CSMA/CD) is a media access control (MAC) method used most notably in early Ethernet technology for local area networking. It uses carrier-sensing to defer transmissions until no other stations are transmitting. What is CSMA CD protocol in networking? Carrier […]

What are the 7 steps for constructing a stem and leaf plot? Steps for Making Stem-and-Leaf Plots Step 1: Determine the smallest and largest number in the data. The game stats are as follows: Step 2: Identify the stems. Step 3: Draw a vertical line and list the stems to the left of the line. […]

How does an open tube manometer work? In its simplest form the manometer is a U-tube about half filled with liquid. With both ends of the tube open, the liquid is at the same height in each leg. When positive pressure is applied to one leg, the liquid is forced down in that leg and […]

What is the net force at constant velocity? When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero. What is the net force acting on an object moving at a […]

What remains constant in isentropic process? An isentropic process is one in which the entropy of the fluid remains constant. This will be true if the process the system goes through is reversible and adiabatic. An isentropic process can also be called a constant entropy process. Isentropic Processes of Ideal Gases with Constant Specific Heats […]

What are the 4 elements of the pass technique for using a fire extinguisher? Select the appropriate type of fire extinguisher. Discharge the extinguisher within its effective range using the P.A.S.S. technique (pull, aim, squeeze, sweep). Back away from an extinguished fire in case it flames up again. When operating a fire extinguisher Remember pass […]

Is the expression for work of a polytropic process restricted to processes of an ideal gas? The specific heats will be discussed later. Notice that the results we obtained for an ideal gas undergoing a polytropic process when n = 1, is identical to that for an ideal gas undergoing the isothermal process….The Polytropic Process: […]
