If air enters with a volume flow of 125 cu.m per min at the rate of 94 m/min and the exit section has a diameter of 350mm, determine a.) the mass flow rate, kg/min b.) the diameter of the entrance section and c.) the exit velocity.

A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.85 L/s, with an output pressure of 3.05 × 105 Pa. a. The water enters a hose with a 2.8 cm inside diameter and rises 2.4 m above the pump. What is its pressure at this point, in pascals? You may neglect frictional losses. ( dont forget to convert the diameters of pipes into meters.) b. The hose then goes over the foundation wall, losing 0.35 m in height, and widens to 4.4 cm in diameter. What is the pressure now, in pascals? You may neglect frictional losses. ( dont forget to convert the diameters of pipes into meters.) Note: answer iS NOT 3.29 x 10^5 for either of these.
