Dr. Nabila Shamim Page 1 Unit Operation CHEG 3023 Homework 1 Due September 14, 2016 1. A closed tank contains compressed air and oil (S.g 0.9) as shown in following Fig. A U-tube manometer using mercury (S.G = 13.62) is connected to the tank as shown. The column heights are h 1 = 36 in., h 2 = 6 in., h 3 = 9 in. Calculate the air pressure. 2. A liquid flows through an orifice located in the side of a tank as shown in Fig. A commonly used equation for determining the volume rate of flow, Q, through the orifice is Q = 0.61 A √( 2 gh) where A is the area of the orifice, g is the acceleration of gravity, and h is the height of the liquid above the orifice. Investigate the dimensional homogeneity of this formula. 3. A dimensionless combination of variables that is important in the study of viscous flow through pipes is called the Reynolds number, Re, defined

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
