1. Calculate the pressure produced by a force
of 800 N acting on an area of 2.0 m^{2}. Answer
(30.0K)
2. The pressure of a gas contained in a cylinder
with a movable piston is 300 Pa. The area of the piston is 0.5 m^{2}. Calculate
the force that is exerted on the piston. Answer
(34.0K)
3. A swimming pool of width 9.0 m and length
24.0 m is filled with water to a depth of 3.0 m. Calculate pressure on the bottom of the
pool due to the water. Answer
(46.0K)
4. What is the pressure on the side wall of
the pool at the junction with the bottom of the pool in the previous problem? Answer
(30.0K)
5. What is the total force on the bottom of
the pool due to the water in the problem 3? Answer
(48.0K)
6. The pressure of a gas in a cylinder with
a movable piston is increased from 40.0 kPa to 60.0 kPa while the temperature
of the gas is held constant. If the original volume of the gas in the cylinder
was 0.9 m^{3} determine
the final volume of the gas after the pressure is increased. Answer
(39.0K)
7. A block of wood of mass 3.5 kg floats in
water. Calculate the buoyant force on the block. Answer
(33.0K)
8. A floating object displaces 0.6 m^{3 } of
water. Calculate the buoyant force on the object and the weight of the object. Answer
(39.0K)
9. A pipe of cross sectional area 80 cm^{2} has
a constriction where the area is reduced to 20 cm^{2}. If the
velocity of the fluid in the larger area is 0.3 m / s what is the velocity
of the fluid in the constricted region? Answer
(37.0K)
10. The pipe in the previous problem is horizontal. If
the pressure in the larger area region is measured as 20 kPa
what is the pressure in the constricted region? Answer
(50.0K)
