The tank depicted in in the diagram is located at an oil refinery. There is rectangular hatch located on one side that gives access for maintenance. The company will be replacing the hatch door and has hired you to assist with the design requirements. a) Describe to the client what is the resultant force and center of pressure on the wall labelled ‘A’ on the diagram above. (P1) b) Calculate the resultant force acting on the hatch door and the location of the centre of pressure.
