please get this right its worth a lot of marks! please answer this in 5 min!

It Ri fg Vo I, The elements in the circuit shown have the following values: R1 = 3276.76 N. R2 = 5371.23 N. R3 = 2628.23 N. Vị = 14.3 V. I, = 0.0123 A. Determine the following: a.) Using superposition, determine V. (in volts): NOTE: Enter numerical values only! Answer in base units (i.e. volts and amps). Graded as: Correct answers are within 5% of solutions a. The value of V, is:

None

solve with nice details draw if possible

3.Question (a) Look up the definition of unit for clothing insulation, called “clo” value. Convert 1.5 clo to a value with an unit in international standard. (b) In the winter, people wear more cloth to keep themselves warm. You have the option of wearing 2 jackets that are 0.3 cm thick or 1 jacket that is 0.6 cm. Assume they are made of the same material and neglect any effect from cloth openings. Which option should you choose to keep you warm? Draw a thermal circuit to help with your discussion.

8- The annual fixed costs for a plant are $100,000, and the variable costs are $140,000 at 70% utilization of available capacity, with net sales of $280,000. What is the breakeven point in units of production if the selling price per unit is $40? 9- A plant has capacity of 4100 hydraulic pumps per month. The fixed cost is $504000 per month. The variable cost is $166 per pump, and sales price is

Can the expert clarify something important for me, which is how to find the load factor consumed? I don't understand the multiplication between the hour and the losses. Example 3.12. The daily demands of three consumers are given below: Time 12 midnight to 8 A.M. 8 A.M. to 2 P.M. 2 P.M. to 4 P.M. 4 P.M. to 10 P.M. 10 P.M. to midnight Consumer 3 No load 200 W Consumer 1 Consumer 2 No load 200 W 600 W No load 200 W 1000 W 800 W No load No load No load 200 W 200 W 1200 W Plot the load curve and find (1) maximum demand of individual consumer (ii) load factor of individual consumer (ii Solution.

F2 * Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. An article in the ASCE Journal of Energy Engineering ("Overview of Reservoir Release Improvements at 20 TVA Dams," Vol. 125, April 1999, pp. 1-17) presents data on dissolved oxygen concentration from streams below 20 dams in the Tennessee Valley Authority system. The sample mean from the observations is X 3.272 and the sample standard deviation is s = 2.130. Assume population is approximately normally distributed.
