The pressure cooker, or "digester" as it used to be called, dates from the seventeenth century and was invented by a Frenchman named Denys Papin. Papin's initial designs didn't include any pressure-release mechanism, which resulted in various explosions early on. Fortunately, Papin subsequently invented a steam-release valve to keep such accidents from happening. In 1938, pressure cooker finally made its way into the home kitchen. A 3 litres capacity of pressure cooker has a small opening with diameter 5 mm. Initially. 2/3 of the volume of the pressure cooker is filled with heated water (saturated water) in atmospheric pressure. Water is then heated with the lid closed. The dead weight is designed to be raised as soon as the temperature reaches to 140 °C. (Note that the atmospheric pressure is 101.325 kPa) Determine: i. the mass water before the lid is closed and the mass of the dead weight used. 11.
