Example 5.3 A process liquid is pumped from a storage tank to a distillation column, using a centrifugal pump. The pipeline is 80 mm internal diameter commercial steel pipe, 100 m long. Miscellaneous losses are equivalent to 600 pipe diameters. The storage tank operates at atmospheric pressure and the column at 1.7 bara. The lowest liquid level in the tank will be 1.5 m above the pump inlet, and the feed point to the column is 3 m above the pump inlet. Plot the system curve on the pump characteristic given in Figure A and determine the operating point and pump efficiency. Properties of the fluid: density 900 kg/m³, viscosity 1.36 mN m⁻²s. Solution Static head Difference in elevation, $\Delta z = 3.0 - 1.5 = 1.5$ m Difference in pressure, $\Delta P = (1.7 - 1.013)10^5 = 0.7 \times 10^5$ N/m² as head of liquid $= (0.7 \times 10^5)/(900 \times 9.8) = 7.9$ m Total static ead $= 1.5 + 7.9 = \underline{9.4}$ m

10. Consider the following sequence of operations on a queue. In this sequence Add(5) means to enqueue 5 onto a queue. Rem() means to dequeue an element off of a queue. Add(4), Add(8), Rem(), Add(7), Add(6), Add(5), Rem(), Rem(), Add(2), Rem(), Add(3), Add(7) Perform these operations on an initially empty queue. What are the contents of the queue after all of these operations are complete? Indicate your answer with a single number in which each digit is an element on the queue. The right-most element (the least significant digit) should be the next element to be dequeued. For example, 321 would indicate a queue with three elements (3, 2, and 1) and 1 would be the next element to be dequeued.
