Water leaves a reservoir at 0.05 m^3/s through a 200-mm riveted steel pipeline that protrudes into the reservoir and then immediately turns a 90º bend with a local (minor) loss coefficient equal to 0.3. Estimate the length of pipeline required for the friction losses to account for 90% of the total losses, which includes both friction losses and minor losses.
A reservoir at elevation 700 ft will supply a second reservoir at elevation 460 ft. The reservoirs are connected by 1300 ft of 24-in cast-iron pipe and 2000 ft of 20-in cast iron pipe in series. What will be the discharge delivered from the upper ..
Five $1,000 bonds having a bond rate of 8% per year payable quarterly are pur chased for $4,940 and kept for 6 years, at which time they are sold. Determine the selling price that yields a 6% effective annual return on the investment.
Air enters an adiabatic nozzle steadily at 300 kPa, 200 o C, and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm 2 . Determine (a) the mass flow raw through the nozzle, (b) the exit temperature of the air, and (c) the ..
