In a railway system with a power source of 600 VDC, I need to achieve a load output of 120 VDC for railway lights. I found a DC-DC converter capable of stepping down 600 VDC to 125 VDC. To obtain 120 VDC from this converter, we can use a voltage divider with the following equation: [R2/(R2+R1)]=120/125=0.96=0.96However, using resistors to achieve the desired output voltage raises some concerns. Is it advisable to use railway-grade resistors for this application? I found some resistors in the range of 1-10k ohms, but I am unsure how they should be connected in the circuit with the lights (the load to be used).
I would greatly appreciate any suggestions or schematic diagrams to clarify the best approach for connecting the resistors in this setup.
I have to develop an efficient parallel numerical integration program on a 2-D mesh but I'm struggling. And it has to be in Cstar

- Chemical Engineering Use the psychrometric chart and demonstrate the linear interpolation method to obtain -0.52 KJ/KgDA. This is the enthalpy deviation. The exercise is uploaded below.arrow_forwardChemical Engineering Use the psychrometric chart. The remaining curves on the psychrometric chart are almost vertical and convex to the left, with labeled values (on Figure 8.4-1) of 0.05, 0.1, 0.2, and so on. (The units of these numbers arekJ/kg DA). Thesecurves are usedto determine theenthalpyof humid air that is not saturated. The procedure is as follows: (a) locate the point on the chart corresponding to air at its specified condition; (b) interpolate to estimate the enthalpy deviation at this point; (c) follow the constant wet-bulb temperature line to the enthalpy scale above the saturation curve, read the value on that scale, and add the enthalpy deviation to it. Also, you will see the exercise on the piece of paper.arrow_forwardWhy is it important for construction project managers to be flexible when dealing with the many variable factors that pop up in a project?arrow_forward
