? ? ? ? ?
1. (a) Explain briefly on the following : heat flux, momentum flux, mass diffusivity
(b) Acetone diffuses into air from an open cylindrical cup of 15 cm diameter. In
a particular case the level of acetone decreased by 4 cm in 10 minutes. The
specific gravity of acetone is 1.36. Calculate the mass flux. [8+8]
2. (a) What is universal gas constant value in CGS system?
(b) What is the volume of 112 gm of nitrogen gas at 200 0C and 3 atm. pr?
(c) What will be the weight of hydrogen of same volume as above at the same
conditions? [3+10+3]
3. (a) Stating the assumptions derive Bernoullis equation.
(b) Sulphuric acid of 98% is to be pumped from a tanker at ground level to, to an
over head storage tank which is 30 m above the ground level through a 5 cm
dia pipe at a flow rate of 30 kg per 10 mins. What is the horsepower required?
[8+8]
4. (a) Write in detail on the classification of fluids by their shear stress shear rate
behaviour illustrate with sketches.
(b) What are single, two and three parameter models for describing a fluid. Briefly
write on any (one) 2 parameter model. [8+8]
5. Derive an expression for mass velocity for isentropic flow through nozzles. [16]
6. (a) What are the different types of settling?
(b) Explain Hindered settling in detail. [4+12]
7. Show that for incompressible flow the losses per unit weight of fluid between the
upstream section and throat of a venturimeter are
KV2
2/2g if K = { (1/Cv)2} { (1 - (D2/D1))4} . [16]
8. What are the different types of pumps? Explain one in detail. [16]
