Looking at the problem again I did forget bouyant force so...
Weight=Bouyant force when an object floats... Analysis of the system bernoullis eqations at three points
1. top of sea water
2. At concrete disc
3. surface of freshwater
Would I calculate the pressures at the points to figure...
Homework Statement
The problem:
There is an illustration and the question is to find the force F to lift a concrete block gate if the the concrete weighs 160 lb/ft3. The block is 3' in diameter and 1' thick. It is in a tank of fresh water 15 ft down. the specific weight of the fresh water...
