Ammonia gas (a) and nitrogen gas (b) are diffusing in counter diffusion through a straight glass tube 2.0 ft (0.610 m) long with an inside diameter of 0.080 ft (24.4 mm) at 298 k and 101.32 kpa. both ends of the tube are connected to large mixed chambers at 101.32 kpa. the partial pressure ofnh3 in one chamber is constant at 20.0 kpa and 6.666 kpa in the other chamber. the diffusivity at' 298 k and 101.32 kpa is 2.30 x 10- 5 m2 /s. (a) calculate the diffusion of nh3, in lb mol/h and kg mol/s. (b) calculate the diffusion n2. (e) calculate the partial pressure at a point 1.0 ft (0.305 m) in the tube and plot pa,pb, and p versus distance z.

The fractional_part function divides the numerator by the denominator, and returns just the fractional part (a number between 0 and 1). Complete the body of the function so that it returns the right number. Note: Since division by 0 produces an error, if the denominator is 0, the function should return 0 instead of attempting the division.

Use the simulation to compare the masses of the three colored and unlabeled weights of different sizes. To do so, set the spring constant of both springs to the same value. Hang known weights on the left spring and an unknown weight on the right spring, and compare the two. Use as many known weights as necessary to determine the unknown masses, and then place each into the appropriate mass bins in the ranking task below. Do the same for all three unknown weights.

Consider an LZW encoder and decoder system works with a table of size 1024 entry. The table is initially filled with entries 0-255 corresponding to the ASCII characters. Characters ‘d and e are located at indices 101 and 102 respectively. Suppose that the LZW decoder receives the following sequence of indices: 101, 102, 256, 258, 257, 260, eof . Determine the original message sent by the encoder and calculate the average code length
