A differential manometer is attached to two tanks, as shown in Fig. between chambers A and B. 1.1 Chamber A SAE 30 oil Mercury Calculate the pressure difference Chamber B Carbon tetrachloride -67.1 KN/m2 O -37.1 KN/m2 O none of the above -57.1 KN/m2 O -47.1 kN/m2 O

Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P5-14. a. Which sequence of operations, (l?2) or (2?1), will yield the greatest recovery of material A? b. What will be the purity of material A using that sequence? c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stesed equation?

Why is it so difficult to process MSW?

Suppose a wet mixture of old bread, leaves, and soil is placed in a pile 1 m tall, and a long thermometer is struck in the middle of the pile. Every other day. the pile is aerated by throwing the mixture into a new pile. Draw a graph showing the temperature in the pile during the first two weeks and explain why these temperature changes occurs.
