In a 45-degree bend pipe on horizontal plane a circular air duct of 3.5 m^2 cross sectional area is gradually reduced to 1.2 m^2 area. Find the pressure in N/cm^2 at 1.5 m^2 cross sectional area, if the velocity of flow at the 2.1 m^2 section is 10.0 m/s and pressure is 3.453 N/cm^2. Take density of air is 1.18 kg/m^3.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Hydraulic fluid with a sg. of 0.78 is flowing through a 1.5 in. i. d. pipe at 58 gal/min. the fluid has an absolute viscosity of 11.8 x 105 lbf-sec/ft2. is the flow laminar, turbulent or within the critical range? give both a numerical reynolds number and a term answer.

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.
