How do you calculate heat load of shell-and-tube heat exchanger? The main basic Heat Exchanger equation is: Q = U x A x ΔTm = The log mean temperature difference ΔTm is: ΔTm = (T1 – t2) – (T2 – t1) = °F. Where: T1 = Inlet tube side fluid temperature; t2 = Outlet shell […]
Why are engineering ethics important?
Why are engineering ethics important? It Gives Them Ability To Push Back Against Bad Decisions It should form part of the culture of engineering, and be celebrated as something to be proud of. A grounding in ethics empowers engineers to bring concerns forward, and ensure that the proper level of scrutiny is applied to unsafe […]
What are the components of graphical user interface?
What are the components of graphical user interface? The main pieces of a GUI are a pointer, icons, windows, menus, scroll bars, and an intuitive input device. Some common GUIs are the ones associated with Microsoft Windows, Mac OSX, Chrome OS, GNOME, KDE, and Android. What is the year that the GUI was designed? 1979 […]
How do you find the frequency of a 555 timer?
How do you find the frequency of a 555 timer? Here the time period is the total time it takes to complete one on/off cycle (T1+T2), while Duty cycle is the percentage of total time for which the output is HIGH….555 Timer Astable Calculator Description. Parameter Formulae Unit Frequency (F) 1.44 / (R1+2×R2) × C1 […]
How does a heat pump heating system work?
How does a heat pump heating system work? To provide heat, a heat pump works by extracting heat from the air outside of your home and transferring it to refrigeration coolant – the coolant is then compressed, which increases the temperature significantly; the coolant is then moved to the indoor unit of the heat pump, […]
What are the 3 parts of the 3D printing process?
What are the 3 parts of the 3D printing process? The 3 Basic Steps of 3D Printing Step #1) Modeling. Before a manufacturing company can build an object with a 3D printer, it must design the model using computer software. Step #2) Printing. The second step of 3D printing involves printing, or building, the object. […]
What happens when carbon content increases in steel?
What happens when carbon content increases in steel? Increasing carbon content increases hardness and strength and improves hardenability. But carbon also increases brittleness and reduces weldability because of its tendency to form martensite. Most steel contains less than 0.35 percent carbon. How does carbon increase the strength of steel? The use of carbon makes iron […]
Why is energy not always conserved?
Why is energy not always conserved? When we don’t ignore outside forces, such as those just mentioned, mechanical energy is not conserved. Energy is “lost” to friction in the sense that it is not converted between potential and kinetic energy but rather into heat energy, which we cannot put back into the object. Can energy […]
How much does it cost to mail a 3 oz letter first class?
What is a 3 part CSI specification?
What is a 3 part CSI specification? CSI’s 3-Part SectionFormat™ divides each specification document into – you guessed it – three parts: General, Products, and Execution. Within each of the three parts is a standard set of article titles set in a standard order to further organize the specification data. How do you write specifications […]
