Consider the system in the following diagram, where there is a viscous element B2, K1 is a translational element, and K2 is a rotational element. Let t(t) be the applied torque, x1 the displacement of M from rest, and u the angular displacement of the element J from rest (i.e., when the springs are neither stretched or compressed). The pulley has no inertia or friction, and the cable does not stretch.
(a) Write the differential equations that describe the system.
(b) Write the state variable equations that describe the system.
The molar specific heat of many materials at low temperatures is found to obey the Debye law C_v = A[T/theta]^3 where A is a constant equal to 1.94 x 10^3 Jmol^-1K^-1 and with the Debye temperature theta taking different values for different mater..

The air-film coefficient at the outside of the insulation may be assumed constant at 2.0 Btu/(h)(ft2)(°F) for all insulation thicknesses
The curie (Ci) is a commonly used unit for measuring nuclear radioactivity: 1 curie of radiation is equal to decay events per second (the number of decay events from 1 g of radium in 1 s).
Assuming that there are no other significant side reactions, calculate masses of alcohol and ether produced, per 1000 kg of allyl chloride fed to the reactor.
The gas flow rate is 4000 kg/hr.sqm of air and the water entering is 6250 kg/hr.sqm. For this system, Henry's law holds good and y = 1.75 x, where y is the mole fraction of acetone in the gas in equilibrium with a mole fraction x in the liquid. Ho..
Calculate the work done in the isothermal reversible expansion of one mole of CH4 (g) from 1.00 dm3 to 10.00 dm3 at 300 K. Treat methane as a van der Waals gas. The van der Waals gas constants for methane are: a=2.3026 dm6⋅bar⋅mol-2 and b=0.043067 dm..
