Question

Page 5 4. A tank is filled with incompressible oil to a depth of (h,) 6.43 m open tank The tank is being drained via a horizontal pipe (radius 1.92 cm), attached at a height of (h,) 0.789 m above the tank bottom Oil is flowing out through the pipe at a rate of 2.34 x 10" m%, but the tank is so large that the descent speed of the oil level at the top is negligible (~0). The gauge pressure in the drain pipe is 51.6 kPa Sensor box 01 The tank's top is open to the atmosphere. A remote sensor (a sealedi box of instruments) is to be placed into the oil. If the sensor has an overall density of 758 kg/m, what percentage of its volume, if any will remain exposed if it floats in the oil? drain pipeoil flow

Please solve and show all the steps and answer (in a neat handwriting or typed !)

Answer 1
