a sample of water has a temperature of 100 degrees Celsius and a pressure of 101.42 kPa. What is its specific density (m^3/kg) and internal energy (kJ/kg)?
When the hydrofoil shown was tested, the minimum pressure on the surface of the foil was found to be 80 kPa absolute when the foil was submerged 1.9 m and towed at a speed of 7 m/s. At the same depth, at what speed will cavitation first occur? Assume irrotational flow for both cases and T = 10 °C. Water = 10°C (50°F) (a) What is the absolute pressure of the atmosphere? kPa (b) What is the specific weight of...
50 grams of water whose temperature is 46°Celsius are added to a thin glass containing 720 grams of water at 20°Celsius (about room temperature). What is the final temperature of the water?
When the hydrofoil shown was tested, the minimum pressure on the surface of the foil was found to be 75 kPa absolute when the foil was submerged 1.8 m and towed at a speed of 6 m/s. At the same depth, at what speed will cavitation first occur? Assume irrotational flow for both cases and T = 10 °C. Water = 10°C (50°F) (a) What is the absolute pressure of the atmosphere? kPa (b) What is the specific weight of...
Hydrogen gas was collected in a tube by water displacement like in your experiment, and adjusted to have pressure inside the tube equal to atmospheric pressure. If the barometer reads 743 mmHg, and the vapor pressure of water is 3 kPa at today's temperature, what is the partial pressure of hvdmpen in the tube?
The air pressure inside the tube of a car tire is 320 kPa at a temperature of 12.0 °C. What is the pressure of the air, if the temperature of the tire increases to 60.5 °C? Assume that the volume of the tube doesn't change. What is the air pressure inside the tube, if the volume of the tube is not constant, but it increases from 23.7 l to 24.4 l during the warming process described above?
When the hydrofoil shown was tested, the minimum pressure on the surface of the foil was found to be 75 kPa absolute when the foil was submerged 1.8 m and towed at a speed of 6 m/s. At the same depth, at what speed will cavitation first occur? Assume irrotational flow for both cases and T = 10 °C. (a) What is the absolute value of the minimum pressure when cavitation occurs? Pcay = kPa (b) What is the value...
When the hydrofoil shown was tested, the minimum pressure on the surface of the foil was found to be 75 kPa absolute when the foil was submerged 1.8 m and towed at a speed of 6 m/s. At the same depth, at what speed will cavitation first occur? Assume irrotational flow for both cases and T = 10 °C. The approach is to determine the pressure coefficient for the minimum pressure at the given speed, and then use this pressure...
Water is siphoned from a large tank and discharges into the atmosphere through a 2-in.-diameter tube as shown in the figure below. The end of the tube is 3 ft below the tank bottom, and viscous effects are negligible. Determine the volume flowrate from the tank. Determine the maximum height, H, over which the water can be siphoned without cavitation occurring. Atmospheric pressure is 14.7 psia, and the water vapor pressure is 0.26 psia
At one end of the Venturi Tube the pressure and speed of flowing water is 25 kPa and 0.05m/s respectively. At another point the pressure is 4 kPa Find the speed of the water at the second point. Answer in m/s
