1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...
4) Volume 2.5 m^3 air in a rigid tank with initial pressure 100 kPa and temperature 25°C There. It is applied to the tank feed line by a valve. Pressure of air flowing through the supply line 600 kPa and temperature is 25°C. By opening the valve, the pressure of the air in the tank is air entering the tank until it is equal to the pressure of the air It is closed. A thermometer placed in the tank lasts...
A tank contains 500 kg of a liquid whose specufic gravity is 2. Determine the volume of the liquid in the tank. 1.29 A tank contains 500 kg of a liquid whose specific gravity is 2. Determine the volume of the liquid in the tank. 130 Clouds can weigh thousands of pounds due to their liquid water content. Often this content is measured in grams per cubic meter g/m3.Assume that a cumulus cloud occupies a volume of one cubic kilometer,...
A compressed-air tank holds 0.470 m^3 of air at a temperature of 283 K and a pressure of 900 kPa . What volume would the air occupy if it were released into the atmosphere, where the pressure is 101 kPa and the temperature is 305 K ?
Draw a diagram of the Carnot cycle on a Pressure-Specific Volume (m^3/kg) diagram for air as a working fluid. Please make sure the horizontal axis is specific volume and not volume.
An adiabatic compressor pressurizes 11 kg/s of air from 60 kPa to 200 kPa. The specific volume and temperature of the air at the compressor inlet are 1.44 m3/kg and 27 C. At the outlet, the specific volume = 1 m3/kg. Cp for air = 1.005 lJ/kg/K. What is the power required to run the compressor?
