No! Pressure is force per unit area: p=f/a. Thus it does not require a large force to produce a large pressure; reducing the area increases the pressure for the same applied force. The thumbtack, for example, can be considered to be a pressure amplifier since a small force applied to the head becomes a very large force at the pointed end of the thumbtack. Not if you have a narrow bore pipe.
No, in fact you would be increasing the pressure. What you would have to do is increase the area while keeping the force constant which then would decrease the pressure.
pressure is not a force but pressure is a force applied in per unit of area
pressure is force divided by area
Bjernkes force is exerted on a gas bubble when the gas bubble is in a liquid, is subjected to an acoustic pressure field, and undergoes volume pulsations. If the acoustic pressure gradient is not zero, it can couple with the bubble oscillation to produce a translational force on the bubble. This force is known as the primary Bjerknes force.
pressure = force / area Therefore pressure and force are directly proportional, meaning... The greater the force the greater the pressure and the lower the force the lower the pressure
