(b) A new energy-efficient electric kettle is designed to boil water quickly and conserve energy. The kettle is rated at 2.5 kW, and it takes 2.5 hours to boil a full kettle of water from room temperature. - Calculate the total amount of electric energy used by the kettle in both kWh and kJ. (2 pts) - If the efficiency of the kettle is 85%, determine the actual energy transferred to the water in KJ. (1 pts) ater in roblem 1 (7 pts) (a) An innovative industrial facility is testing a new liquid, TechFluid-98, for use in their cooling systems. They are using a U-tube manometer to measure the pressure difference across a section of a cooling pipe here TechFluid-98 is flowing. The manometer uses mercury (density = 13,600 kg/m³) as the manometric fluid, and the density of TechFluid-98 is 1,200 kg/m³. Calculate the gauge and absolute pressure in the pipe where TechFluid-98 is flowing. (4 pts) Po = 101 kPa 0.3 m TechFluid-98 0.15 m mercury 0.1 m
