It is estimated that the operating rate of a major manufacturer's factories over a certain 365-day period is given by $f(t) = 100 + \frac{800t}{t^2 + 90,000}$ percent, $0 \le t \le 365$. Determine the day on which the operating rate is maximized. What is the maximum operating rate? Round to the nearest tenth.

The figure shows three charges q1, q2 and q3 situated at corners of a rectangle of sides a = 14.0 cm and b = 6.0 cm. For q1 = 4.80 µC, q2 = -4.80 µC, and q3 = 2.40 µC find the electric potential at the center of the rectangle. 2.83×105 V Continuing with the figure above, how much of the electric energy of the system would be expended in moving q3 to infinity while q1 and q2 remain in their positions?

Task (2) The water needs of a small farm are to be met by pumping water from a well that can supply water continuously at a rate of 5 L/min. The water level in the well is 13 m below the ground level, and water is to be pumped to the farm by a 2-cm internal diameter plastic pipe. The required length of piping is measured to be 20 m, and the total minor loss coefficient due to the use of elbows, vanes, etc. is estimated to be 8.5. Taking the efficiency of the pump to be 70 percent. The viscosity of water is 0.0025 kg/m-s. a) Define the type of flow using Reynolds number. b) Explain the significance of the information we get from Reynolds number equation. c) determine the rated power of the pump that needs to be purchased.
