Only need help with 11.6. Please and thank you
11.5 The cylindrical piston shown in Figure 11.18(I) is filled with water (? = 1000 kg m−3). The piston itself can be considered weightless and the whole system is surrounded by air at a pressure of 100 kPa.
(a) What is the absolute pressure in the water at each of the points A, B, and C when there is no weight on the piston?
(b) What is the gauge pressure in the water at each of the points A, B, and C under these circumstances?
A mass of 5 kg is then placed on the piston as shown in Figure 11.18(II).
(c) What is the absolute pressure in the water at each of the points now?
(d) What is the gauge pressure in the water at each of the points now?
11.6 Repeat problem11.5where the fluid is Silica Gel. (? = 700 kg m−3)
