Force is related to velocity through Newton's second law, which states that force is directly proportional to the acceleration of an object. Mathematically, force (F) = mass (m) x acceleration (a). Acceleration is directly related to velocity, as a change in velocity over time results in acceleration. Therefore, force can indirectly be related to velocity through its influence on acceleration.
Pressure is defined as the amount of force exerted on an object (in Newtons) divided by the area over which the force is exerted (in meters). Velocity is defined as the displacement of an object (in meters) divided by the time interval over which the object was displaced (in seconds).
Velocity pressure is the pressure exerted by the movement of a fluid, while static pressure is the pressure exerted by the fluid when it is not in motion. In fluid dynamics, velocity pressure is related to the speed of the fluid flow, while static pressure is related to the fluid's potential energy.
Power is the rate at which work is done or energy is transferred. It is calculated as the product of force and velocity, where power = force x velocity. This means that power increases with both force and velocity.
Force, pressure, and area are related through the equation pressure = force / area. This means that pressure is directly proportional to force and inversely proportional to area. Increasing force applied on a given area will increase the pressure, while increasing the area over which the force is applied will decrease the pressure.

mass, acceleration, motion - speed and velocity, newtons 1st law force = mass * acceleration speed requires force to change force acts on velocity to change it newtons 1st law describes force
In a fluid, the velocity and pressure are related by Bernoulli's principle, which states that as the velocity of a fluid increases, its pressure decreases, and vice versa. This relationship is often seen in applications such as fluid dynamics and aerodynamics.
Newton's second law of motion mathematically relates acceleration to force as F = ma, where F is the force applied to an object, m is its mass, and a is its acceleration. Acceleration is also related to velocity through the equation a = Δv/t, where Δv is the change in velocity over time t. So, Newton's laws help explain the relationship between acceleration, velocity, and force.
Velocity ratio is calculated as the ratio of the input velocity to the output velocity of the hydraulic machine. Pressure efficiency is the ratio of the output power to the input power, taking into account losses due to pressure drops and inefficiencies in the system. Load in a hydraulic machine is determined by the force acting on the piston or cylinder, which can be calculated using the formula force = pressure x area.
Pressure is defined as the force per area.
