Ch8, Calculating Pressure

In a hydraulic jack, you have 1,000 lbs of force being applied to a 3" piston with a surface area of 7.065 square inches. What is the fluid pressure within the jack?
(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

If you need to be able to lift 750 lbs with a pallet jack, and you need to design a system using a piston with a surface area of 6.54", what would the diameter of the piston need to be given a pressure being applied of 55 psi? Round your answer to the nearest inch.
(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

If a force of 500 lbs is being applied to a piston with a surface area of 2.5 square inches. What is the fluid pressure within the jack?
(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

As an airplane is flying at 30,000 feet, the outside pressure is 4.3 psi. The airplane windows are 16" x 20". What is the force (in lbs) being applied to the window?
(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

If wind is blowing against at surface that is 36" x 36" at a pressure of 17 psi, what is the force (in lbs) being applied to the surface?
(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

If the pressure is on a surface is 52 psi, and the surface measures 17" x 8", what is the force (in lbs) being applied to the surface?
(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

A hydraulic system exerts a pressure of 50 psi on a cylinder. If the desired output force is 250 lbs, what diameter is required for the cylinder?

(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

A fluid system exerts a pressure of 250 psi on a cylinder, and the desired output force is 10,000 lbs, what diameter is required for the cylinder to lift the weight of the load?

(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

If you are designing a hydraulic lift system to lift a car that will have a max load of 7,500 lbs, and you are going to be using 175 psi to lift the pistons, and you are going to use 4 pistons (one in each corner), what would the diameter of each cylinder need to be if they were all the same size?

(TIP: Do NOT use commas in your answer.
If you must use decimals, round to the nearest hundredth position.)

If a force of 250lb was applied to a surface that was 6" x 6", what kind of pressure would be the result in psi?
