(Rigid body rotation) Derive the equation for the shape of the surface zsurf(rsurf) for a rigid-body rotation of water at angular speed (rad/sec). Follow this process:
1) Start with pressure gradient in cylindrical coordinates:
2) Write out force balance in r and z directions
3) Integrate using the method we did in class: F = ma in r-direction gives: P(r,z) = P(r) + f1(z) F = ma in z-direction gives: P(r,z) = P(z) + f2(r)
4) Solve for z(r) at surface, where P = Patm = constant
Derive and expression for force exerted by a jet of water on fixed vertical plate in direction of
Illustrate following key terms with suitable example :- (a) Co-planar parallel force. (b) Co-planar non concurrent force. (c) Non co-planar concurrent force.
Globular Transfer Globular transfer is characterised by a drop size of greater diameter than that of the electrode wire. The large drop is easily acted on by gravity, generall
Inlet and Exhaust Valves : Valves are commonly mushroom shaped poppet type. They are provided on the cylinder for regulation of the charge coming into the cylinder (inlet valve)
A rod of 80mm diameter and 10mm length with thermal conductivity 16W/m-deg protrudes from a surface at 160 o C. The rod is exposed to air at 30 o C with convective coefficient of
Split Queue Rules SPT* Two queues prioritized as per to SPT. The operations for that t sj - u is negative form a high priority queue that is processed first. The order insid
Draw the P-h and T-S diagram for the vapour compression cycle when the vapour after compression is : (i) wet region (ii) dry saturated
Define Thermodynamics Thermodynamics is the science which deals with the conversion of heat into mechanical energy. It is relies upon observations of general experience, which
