- For a certain polyatomic ideal gas the value R is 0.354 kJ/(kg.K). Determine its molecular weight ( W ), both specific heat at constant pressure ( Cp ) and at constant volume ( Cy ).arrow_forwardSubject Thermodynamics. Instructions: Don't round off in the process. Just round off in the final answer with 2 decimals only. Use 273.15 K to convert Celsius to Kelvin.arrow_forwardA volume of 400 cc of air is measured at a pressure of 740 mm Hg absolute and a temperature of 18 ˚C. What will be the volume (in cc) at 760 mm Hg and 0 ˚C?arrow_forward
- Temperature of nitrogen in a vessel of volume 2 m' is 288 K. A U-tube manometer connected to the vessel shows a reading of 7 cm of mercury (level higher in the end open to atmosphere). The universal gas constant is 8314 J/kg-mol-K, atmospheric pressure is L01325 bar, acceleration due to gravity is 981m/s² and density of mercury is 13600 kg / m’. The mass of nitrogen (in kg) in the vessel is 3arrow_forwardThe figure shows a 50.-kg frictionless cylindrical piston that floats on 20 mol of compressed air at 45.°C. How far does the piston move if the temperature is increased to 600 °F? (This is an Isobaric process and the piston is at sea level under an atmospheric pressure of 101.3 kPa). The values given in the figure are: 50. Kg, 30.°C, and 10. cm.arrow_forwardThe Louisiana Superdome has an interior volume of 125 million ft3, covered by a 440,000 ft² roof. On a particular day, the interior air pressure gave a manometer reading of 19 inches mercury (pHg = 13.6 g/cm³). Local atmospheric pressure is 102 kPa. 1. kg Calculate the mass of the air inside, assuming an average temperature of 20 °C. 2. kN Calculate the net force applied to the roof by the interior/exterior air (do not account for the weight of the roof). Assume the roof is flat.arrow_forward
- T F The specific weight of a fluid is the product of the fluid's density and the acceleration due to gravity. Stronger surface tension leads to higher capillary rise. Absolute pressures are frequently negative. If the pressure of fluid drops below the vapor pressure of that fluid at that temperature, the fluid will cavitate. F F T F F Density can be measured in lb;/ft° in the English system of units. For a hydrostatic incompressible fluid, pressure is independent of depth. A fluid with a high bulk modulus of elasticity is more difficult to compress than one with a low bulk modulus of elasticity. Viscosity is caused, in part, by the surface tension within a fluid. A fluid can resist an applied shear stress by deforming. Pressure increases faster with depth in less dense fluids than in more dense fluids. T F F F F Farrow_forwardThe pressure at 9.85m depth in a fluid is 102,482Pa. Calculate the density of the fluid and present the answer in Pascal with accuracy up to one decimal place. Consider 1 atm = 101325 Pa. Assume the value of gravity to be 9.8 m/s2.arrow_forwardAs shown in the diagram, the state of helium gas is changed in such a way that its PV graph is a straight line segment with volume Vo increases to yVo and pressure Po increases to xPo where x and y are arbitrary constants. During this process the total heat transferred to the gas is equal to the heat necessary to double the absolute temperature of the gas at constant volume. What is the maximum ratio for the volume increase? xP, P. Voarrow_forward
- A pressure gauge fitted on the side of a tank filled with liquid reads 50 kPa and 100 kPa at heights of 5 m and 10 m.What is the approximate density of the liquid (in kg/m)? (take g = 10)..arrow_forwardThe pressure difference between an oil pipe and water pipe is measured by a double-fluid manometer, as shown. For the given fluid heights and specific gravities, calculate the pressure difference in kPa.arrow_forwardTHERMODYNAMICS SUBJECT NEED ASAP Two spherical vessels of different sizes contain the same gas and are connected by means of a pipe with a valve. Sphere A has a diameter of 5 foot at the given pressure gauge of 50 kgf/cm². Sphere B contains the same gas at 20 kgf/cm² gauge. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 36 kgf/cm². The temperature at the two vessels before and after opening the valve is maintained at 21.1°C. If the barometric pressure is 750 torr and the gas inside the sphere is nitrogen, find the following: The atmospheric pressure in psi The diameter of Sphere B The total mass of the gas after opening the valve I hope you can all answer this question I know tutor can answer until 4 parts.
