A pressure cooker cooks a lot faster than an ordinary pan by maintaining a higher pressure and temperature inside. The lid of the pressure cooker is well sealed, and steam can escape only through an opening in the middle of the lid. A separate metal piece, the petcock, sits on top of this opening and prevents steam from escaping until the pressure force overcomes the weight of the petcock. If the mass of the petcock in a particular pressure cooker is 50 grams, and has an opening cross-sectional area of 4 mm2, what is the operation pressure inside the cooker? Assume an atmospheric pressure of 101 kPa.
