Thrust, usually called push or pull, is the force that the cylinder exerts in pounds. Push is the force exerted at the eye of the piston rod when pressure is placed upon the full diameter of the piston. Pull is the force exerted at the rod eye when pressure is directed against the rod side of the piston. Pull is always less than push because of the reduction of cylinder area through presence of the cylinder piston rod. To find the exact push capacity of a cylinder, multiply the square inches of piston face area by the cylinder pressure in pounds per square inch (piston area X psi). To find the exact pull capacity, use the same formula, but deduct the square inches of rod area from the piston face area (piston area minus rod area) X psi.
Push = A X P
Pull = [A - (.785 x d2)] X P
A = Cylinder area in square inches
P = Working pressure of pump in psi
D = Piston rod diameter in inches
Where new and different size cylinders can be safely installed to operate an implement, it is extremely important to provide a good safety factor in designing and fabricating mounting brackets for the new cylinder. Such a safety factor should allow for the hydraulic system's maximum relief pressure, as well as possible surges.

There is no way to determine it. The pushing capacity is determined by the size of the piston; if it is 2 square inches, the pump can lift 6000 pounds.

depends on the cylinder length and diameter
