Calculate the number of teeth on the driven gear?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.
