A new plane is equipped with a piezometer at point A and a pitot tube at point B. The piezometer indicates an absolute pressure of 47.2 kPa, while the Pitot tube reads an absolute pressure of49.6 kPa. Determine the altitude of the plane and its speed.

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
