a）Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force (in N) must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 22.0 cm in diameter and the gauge pressure inside is 2.70 atm? Neglect the weight of the lid. N b）A crass host pours the remnants of several bottles of...

The piston (Figure 2) has fluid on both sides. The gage pressure
below the piston P1 = 25 kPa and the absolute pressure above the
piston P2 = 80 kPa . What force F must be applied to the piston to
keep it stationary? The diameter D = 10 cm . Neglect the magnitude
of the force due to Patm acting on the rod relative to the

A pressure cooker is a pot whose lid can be tightly sealed to prevent gas from entering or escaping. If an otherwise empty pressure cooker is filled with air of room temperature and then placed on a hot stove, what would be the magnitude of the net force F120 on the lid when the air inside the cooker had been heated to 120C ? Assume that the temperature of the air outside the pressure cooker is 20C(room temperature) and that...

A pump increases the water pressure from 100 kPa at the inlet to 900 kPa at the outlet. Water enters this pump at 15 degree C through a 1-cm-diameter opening and exits through a 1.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. Will these velocities change significantly if the inlet temperature is raised to 40 degree C?
