Argon at 20 degrees C and 100kPa has a velocity of 27 m/s and enters a constant diameter pipe of 18mm. As the argon passes through the pipe, it is heated in a steady flow process to 100 degrees C. The pressure at that point is 28 kPa. No work is being done. Calculate the rate of heat transfer (Q).
Carbon dioxide enters an adiabatic compressor at 100kPa and 300K at a rate of 0.5kg/s and exits at 600kPa and 450K. Considering constant specific heat, determine (a) isentropic efficiency of the compressor (b) the rate of entropy change in (kW/K) ..
What volumetric flow rate of fuel gas is required if there are no heat losses to the surroundings?
Calculate the modulus of elasticity of the aluminium alloy. Use the modulus to determine the length of a 1.25 m bar to which a stress of 210 MPa is applied.
Find the velocity of the bullet and the distance it has traveled into the water after 4 seconds. Please show detailed step by step process to solution.
Neglecting the mass of the rod and the effect of friction, determine the radial and transverse components of the velocity of the collar when r = 0.5 m.
