1. Find absolute pressure, given 9.7 psi vacuum.
2. Calculate kinematic viscosity of air at 80°F and 60 psia.
3. A pipe with an inside diameter of 18 in contains water to a depth of 15in. Find the hydraulic radius.
4. Points A and B are separated by 2000 ft of new 8 inch schedule 40 steel pipe. 500 gal/min of 70°F water flows from A to B. Point B is 50 ft above point A. Pressure at B is 50psig, what is the pressure at A?
5. A cylindrical tank 30 ft tall (full) and 15 ft in diameter has a 6 inch hole in the bottom. Coefficient of discharge = 0.99 How long will it take the water to drop from 30 feet to 20 feet?
6. 1500 gal/min of 70°F thickened sludge with SG of 1.1 flows through a pump with an inlet diameter of 10 in and an outlet diameter of 6 in, centerlines at same elevation. Inlet pressure is 7 in Hg (vacuum). A discharge pressure gauge 3 ft above the pump discharge centerline reads 25psig. The pump efficiency is 85%. All pipes are schedule 40. What is the input power of the pump?
7. A double suction water pump moving 250 gal/sec turns at 800 rpm. The pump adds 15 ft of head to the water. What is the specific speed?
8. A horizontal turbine reduces 150 ft^3/sec of water from 25 psia to 5 psia. Friction is negligible. What power is developed?
**** I will post these when I write them, but before I solve them, so I have no idea if they are even solvable.****
****I will post answers within 24 hours****
