Q: A pressurized 2-m-diameter tank of water has a

A pressurized 2-m-diameter tank of water has a 10-cm-diameter orifice at the bottom, where water discharges to the atmosphere. The water level initially is 3 m above the outlet. The tank air pressure...

Q: A very large tank contains air at 102 kPa at a location

A very large tank contains air at 102 kPa at a location where the atmospheric air is at 100 kPa and 20°C. Now a 2-cm-diameter tap is opened. Determine the maximum flow rate of air through t...

Q: What is an adiabatic process? What is an adiabatic system?

What is an adiabatic process? What is an adiabatic system?

Q: Water is flowing through a Venturi meter whose diameter is 7 cm

Water is flowing through a Venturi meter whose diameter is 7 cm at the entrance part and 4 cm at the throat. The pressure is measured to be 380 kPa at the entrance and 200 kPa at the throat. Neglectin...

Q: How is the location of the hydraulic grade line determined for open

How is the location of the hydraulic grade line determined for open-channel flow? How is it determined at the outlet of a pipe discharging to the atmosphere?

Q: Water flows at a rate of 0.011 m3/s

Water flows at a rate of 0.011 m3/s in a horizontal pipe whose diameter increases from 6 to 11 cm by an enlargement section. If the head loss across the enlargement section is 0.65 m and the kinetic e...

Q: Air flows through a pipe at a rate of 120 L/

Air flows through a pipe at a rate of 120 L/s. The pipe consists of two sections of diameters 22 cm and 10 cm with a smooth reducing section that connects them. The pressure difference between the two...

Q: A 3-m-high large tank is initially filled with

A 3-m-high large tank is initially filled with water. The tank water surface is open to the atmosphere, and a sharp-edged 10-cm-diameter orifice at the bottom drains to the atmosphere through a horizo...

Q: Reconsider Prob. 12–72. Using appropriate software, investigate

Reconsider Prob. 12–72. Using appropriate software, investigate the effect of the tank height on the initial discharge velocity of water from the completely filled tank. Let the tank...

Q: Reconsider Prob. 12–72. In order to drain the

Reconsider Prob. 12–72. In order to drain the tank faster, a pump is installed near the tank exit. Determine the pump head input necessary to establish an average water velocity of 6...
