Can you please help me with the following circled problems? Thanks so much!

Find the work W required to empty the tank in Figure 8 through the m and hole at the top if the tank is half full of water. G = 6.6. Assume the tank in Figure 8 is full of water and let W be the 35. 3to work required to pump out half of the water through the hole at the top Do you expect W to equal the work computed in Exercise 237 Explain and equal to then compute W. 36. Use 15. Assume the tank in Figure 10 is full. Find the work required to pump a 2000-1 out half of the water. Hint: First, determine the level H at which the water Assume remaining in the tank is equal to one-half the total capacity of the tank. Me = 5. 26. Assume that the tank in Figure 10 is full.
