Q1: Water flows into a process unit through a 5-cm ID pipe at a rate of m3/h. Calculate Ėk for this stream in joules/second.
Q2: Water is pumped from one reservoir to another 290 ft away. The water level in the second reservoir is 55 ft above the water level of the first reservoir. What is the increase in specific potential energy of the water in Btu/lbm?
Q3: Kerosene oil is pumped at a rate of 35.0 kg/s from a point 335 meters below the earth’s surface to a point 40 meters above the ground level. Calculate the attendant rate of increase of potential energy.
Q4: Water is pumped from a large tank into a pipe of 3.00 cm inner diameter at the rate of m3/s. what is the specific kinetic energy of the water?
