Problem 32PE
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 must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 25.0 cm in diameter and the gauge pressure inside is 300 atm? Neglect the weight of the lid.

QUESTION:
Problem 32PE
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 must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 25.0 cm in diameter and the gauge pressure inside is 300 atm? Neglect the weight of the lid.
ANSWER:
Solution to 32PE
Step 1 of 2
We need find the force that the latches of the pressure cooker will withhold if the gauge pressure is
Gauge pressure is above the atmospheric pressure. We will neglect the atmospheric pressure in this case.
We know that,
Given data:
Gauge pressure
Diameter of the lid,
Radius of the lid,
Area of the circular lid,
