- 3. A steam power plant has an average monthly net power delivery of 740 MW over the course of a year. This power delivery is accomplished by burning coal in the boiler. The coal has a heating value of 9150 Btu/lbm. The cost of the coal is $14.20/ton. The overall thermal efficiency of the plant is, nth = Wnet Qboiler = 0.26 = 26% Determine the annual cost of the coal required to deliver the given average monthly power.arrow_forward47 14 16 12 34 10 12 12 33arrow_forward= The forces F₁ = 590 lb, F₂ = 380 lb, F3 = 240 lb and F 330 lb.

- A bent pipe is attached to a wall with brackets as shown. A force of F = 180 lb is applied to the end of the tube with direction indicated by the dimensions in the figure. Determine the support reactions at the brackets B, C, and D. Model these brackets as journal bearings (only force reactions perpendicular to the axis of the tube) and neglect couple moment reactions. Assume the distance between the supports at B and C and the tube bends nearby are negligible such that the support at C is directly above the support at D and the dimension g gives the distance between supports B and C.
