Air p = 50 kPa Oil NO (a) 2 m 0.6 m Consider the oil tank shown in figure. The manometer placed on top of the tank measures 50 kPa of pressure. Determine amplitude and center of application of the total pressure force applied to the square plug plate (length edge=0.6 m). Assume a reasonable value for the specific weight of oil at ambient temperature. Use both techniques of infinitesimals and volume prisms learned in class and show that they lead to the same results. Explain and comments all your steps.
