      🎯 Tests for Bitumen 🎯  👉 Penetration Test :- Hardness  👉  Float Test :- Consistency  👉 Ring Ball Test :- Softening Point  👉 Spot Test:- TO Check Bitumen Is Cracked Or Uncracked.

🎯  Units of parameters in Fluid Mechanics 🎯  👉  Mass=kg  👉 Weight or Force = N =kg-m/s2  👉 Mass density =kg/m3  👉 Weight density or Unit weight or specific weight =N/m3  👉 Specific volume =m3/kg  👉  Shear stress = N/m2  👉 Dynamic viscosity or Coefficient of viscosity    💥   SI unit  =N-sec/m2=Pa-sec =kg/m-sec   💥  CGS unit = dyne-sec/cm2 =gm/cm-sec =1Poise =0.1N-sec/m2  👉 Kinematic Viscosity     💥 SI unit= m2/sec     💥 CGS unit = cm2/sec= 1 stokes   👉 Bulk modulus = N/m2   👉 Surface tension = N/m   👉 Capillary rise or fall =m   👉 Pressure = N/m2.
