3 dni temu · The formula for calculating the density of an object using water displacement is given by: \ [ D = \frac {m} {FW - IW} \] where: \ (D\) is the density in grams per cubic centimeter (g/cm³), \ (m\) is the mass of the object in grams, \ (FW\) is the final water level in milliliters (mL), \ (IW\) is the initial water level in milliliters (mL).
1 dzień temu · The core of the Boat Speed Calculator lies in Crouch's formula: \[ S = \sqrt{\frac{P}{D}} \times C \] where: \(S\) represents the boat's top speed in miles per hour, \(P\) is the power supplied to the boat in horsepower, \(D\) is the displacement of the boat in pounds, \(C\) is the Crouch constant, specific to the boat's type.

The barge is now sunk due to bilging. Calculate the force required to lift the vessel from the sea bed if the relative densities of sea water, iron and wood are ( 1.025,7.05 ) and 0.8 respectively.(30.
