The shaft of the flywheel shown in Figure is supported on bearings. A light cord is wound around the shaft from which is hung a 2 kg mass. When allowed to fall freely the mass accelerates uniformly through a distance of 2 m in 3 s. The friction couple in the bearings is estimated to be 0.35 Nm. Calculate the moment of inertia and radius of gyration of the assembly.
Pure methane initially at 3000 psi, 65 oF enters a pipeline of 12-in inside diameter, at a rate of 70 lb/s. Using the generalized compressibility factor chart, calculate the inlet density and initial velocity of methane.
a particle travels along a straight line such that in 2 s it moves from an initial position sa 0.5m to a position sb
consider a water pipe of length l17m inner radius r115cm outer radius r220cm and thermal conductivity k14wmk. heat is
The space between two 6 in. long concentric cylinders is filled with glycerin (viscosity = 8.5X10-3 lb s/ft2). The inner cylinder has a radius of 3 in. and the gap width between the cylinders is 0.1 in. Determine the torque AND power required to rota..
a piston cylinder device having an initial volume of 2 m3 initially contains steam at 10 bars and 200oc state 1. the
water exiting the condenser of a power plant at 38ordmc enters a cooling tower with a mass flow rate of 4.5 x 107 kgh.
Consider a Refrigerant 22 at 0oC that is going through a phase change from the saturated liquid to saturated vapor. Using T-dS equations, calculate the entropy change between these two phases.
Steam at a pressure of 0.08 bar and a quality of 93.2% enters a shell-and-tube heat exchanger where it condenses on the outside of tubes through which cooling water flows, exiting as saturated liquid at 0.08 bar. The mass flow rate of the condensing ..
a particle is traveling with a velocity of v 3sqrtte-0.2ti 4e-0.8t2j ms where t is in seconds. determine the magnitude
why is the correct tightening of friction grip bolts important?
A batch of a certain substance (a simple system) is held in a constant volume, rigid container. The system experiences an infinitesimal change of state during which the pressure rises. The question is whether during this constant volume pressurisatio..
