    Undergrad How Do You Calculate Thrust on a Circular Trap Door Immersed in Oil?

    I tried using P=pgh. Which works out as 700*9.81*3.6= 24.7212kN Then thought many had to put that int P=FA. Which as area is Pi r^2 area works out as 2.54m^2 That gave me 62.7918kN. I have used 1/2pgbh^2 to find out thrust on submerge rectangular objects but couldn't make that one work...

    Undergrad How Do You Calculate Thrust on a Circular Trap Door Immersed in Oil?

    A fuel tank contains oil of a relative density of 0.7 on one side there is a circular trap door of 1.8m in diameter. The fuel level is 1.8m above the top edge of the door calculate the thrust on the door.
