Fluid Dynamics of Fires

a). From the definition of pressure P, it can be expressed as, P= F/A, where F is the applied force and A is the cross sectional area of the surface of the material. Since the hydraulic cylinder has two radial cylinders the pressure at each cylinder can be expressed as taking the subscripts 1 & 2 to represent the cylinders, then at the smaller cylinder 1, P=F1/A1 and at larger cylinders 2, P= F2/A2. But A1= ? R12 and A2…
