- B=6, so the feeder reactance is 16 %. Fig. Q2 shows a typical network of a small power station. Calculate the fault level at busbar C using 36 MVA as the base. The feeder reactance is 16 %.arrow_forwardDETERMINING CAPACITY UTILIZATION AND EFFICIENCY Sara James Bakery has a plant for processing Deluxe breakfast rolls and wants to better understandits capability. Last week the facility produced 148,000 rolls. The effective capacity is 175,000 rolls. Theproduction line operates 7 days per week, with three 8-hour shifts per day. The line was designed toprocess the nut-filled, cinnamon-flavored Deluxe roll at a rate of 1,200 per hour. Determine the designcapacity, utilization, and efficiency for this plant when producing this Deluxe roll. APPROACH c First compute the design capacity and then use Equation (S7-1) to determine utiliza-tion and Equation (S7-2) to determine efficiency.arrow_forward1 - A square chip, with side ? = 5 mm, operates under isothermal conditions.The chip is positioned on a substrate so that its side and bottom surfaces are thermally insulated, while its top surface is exposed to theflow of a refrigerant at ?∞ = 15°C. From reliability considerations, the chip temperature cannot exceed ? = 85°C. The refrigerant being air, with a convection heat transfer coefficientcorresponding ℎ = 200 W/(m2K), what is the maximum allowable power for the chip? Since the coolant is a dielectric liquid for which ℎ = 3000 W/(m2K), what is the maximum allowed power?arrow_forward

Specify your reason.arrow_forwardDetermine if the systems given below are Static or Dynamic, Causal or non-causal, Linear or non-linear, Time-invariant or time varying and Stable or unstable. 2. Y2(n)=x(n)+nx(n+1)arrow_forwardBased on Professional Morality, explain the following professional engineering scenario wherein two(2) electrical engineers are paid to prepare Electrical System Design of a high-rise mixed commercial and residential building. The first engineer's design leans towards the safety operation and maintenance of building, whereas the other engineer's design favors initial cost of the project. Provide at least three (3) instances that its more reasonable to choose a design that has favored safety over economical criteria of the design.arrow_forward
- A resistive touch screen has 640 pixels in the x-direction and 1024pixels in the y-direction. The resistive grid has 8 V applied in both the xandy-directions. The pixel coordinates at the touch point are (480, 192). Suppose the resistive touch screen described above is simultaneously touched at two points, one with coordinates (480, 192) and the other with coordinates (240, 384).1. a) Calculate the voltage measured in the x- and y-grids.2. b) Which touch point has your calculation in (a) identified?arrow_forwardThe outside diameter of a coaxial cylindrical electrode system is given as 30 cm.

The original of the problem is attached.arrow_forwardRegional Maritime University (RMU) campus has 200 classrooms and 400 faculty offices. The classrooms are equipped with 12 fluorescent tubes, each consuming 110 W, including the electricity used by the ballasts. The faculty offices, on average, have half as many tubes. The campus is open 240 days a year. The classrooms and faculty offices are not occupied an average of 4 h a day, but the lights are kept on. If the unit cost of electricity is GH₵ 0.082/kWh, determine how much the campus will save a year if the lights in the classrooms and faculty offices are turned off during unoccupied periods.arrow_forwardF.)
