A Circular plate having a diameter of 30mm is held perpendicular to an axisymmetric horizontal jet of air having a velocity of 40m/s and a diameter of 80mm as shown in the figure. A hole at the center of the plate results in a discharge jet of air having a velocity of 40m/s and a diameter of 20mm. Determine the horizontal component of force required to hold the plate stationary.
an air-standard dual cycle has a compression ratio of 18 and a cutoff ratio of 1.1. the pressure ratio during
The pressure in a tire depends on the temperature of the air in the tire. The gage pressure of an automobile tire with a volume of 0.025 m3 is measured to be 210 kPa at 25 oC at sea level on a day with calm weather. If the temperature of the air in t..
what is the deflection wt of a simply supported beam of varying load pt w.r.t time applied at center. consider maxwell
The capillary rise, h, of a liquid in a tube varies with tube diameter, d, gravity, g, fluid density, p, surface tension, Y, and the contact angle, B. (a) Find the dimensionless form of this statement. (b) If h = 3 [cm] in a given experiment, what wi..
A gas turbine receives a mixture having the following molar analysis: 10% CO2, 19% H2O, 71% N2 at 720 K, 0.35 MPa and a volumetric flow rate of 3.2 m3 /s. The mixture exits the turbine at 380 K, 0.11 MPa. For adiabatic operation with negligible kinet..
Determine the internal energy change as saturated liquid steam at 60?F goes to a two phase mixture of quality 0.40 at 60?F. Provide answers in SI units. Determine the final fluid phase and the enthalpy change.
A pressure cooker has a volume of 0.011 m3 and initially contains a two-phase liquid-vapor mixture of H2O at a temperature of 100o C and a quality of 10%. As the water is heated at a constant volume, the pressure rises to 2 bar and the quality become..
air at 640k and 8 bar is expanded through a turbine to a final temperature of 350k. what is the work done for 1kg of
Steam enters an insulated de-super heater operating at steady state at 3 MPa and 320°C, where it is mixed with liquid water at 2.5 MPa and 200°C to produce saturated vapor at 2 MPa. Neglect kinetic and potential energy changes, determine the mass flo..
