State whether the following statements are true or false. Also, very briefly mention the reason if the statement is false. i. TOFO Surfactants increase the surface tension of water. ii. TOFO The Mach number of an aircraft cruising at a constant velocity in still air may be different at different locations. iii. TOFO Nonuniform heating can change the vorticity of a fluid eleinent. iv. TOFO The value of momentum correction factor is more for a turbulent flow than for a laminar How. Y. TOF Gradual contraction results in greater minor loss coefficient than gradual expansion. State whether the following statements are true or false.
