Equipment is placed in service on january 1. the cost of the equipment is $250,000 with a salvage value of $25,000 and an estimated useful life of five years. What amount of annual depreciation expense should be recorded on December 31 of Year 2 under the sum-of-years'-digits method?

Python has to offer.

Features and Application Areas of Python

If you are already familiar with Python and its features and application areas, please feel free to take notes. In the next video, we will dive deeper into the topic.

The elementary gas-phase reaction

(CH)COOC(CH3)3 → C2H6 + 2CH;COCH,

is carried out isothermally in a flow reactor. The specific reaction rate at 50°C is 10* min' and the activation energy is 85 kJ/mol. Pure di-tert-butyl peroxide enters the reactor at 10 atm and 127°C and a molar flow rate of 2.5 mol/min. Calculate the reactor volume and space time to achieve 90% conversion in:

(a). (b).

(C).

(d).

a mixed flow reactor a plug flow reactor

If this reaction is to be carried out isothermally at 127°C and an initial pressure of 10 atm in a constant-volume batch reactor with 90% conversion, how long would it take?

Assume that the reaction is reversible *with equilibrium constant,

Кс = 0.025 mol?

liter, calculate the equilibrium conversion; then redo (a) through (c)

to achieve a conversion that is 90% of the equilibrium conversion.

[Universal gas constant, R = 8.314 J/mol.K = 0.08206 (liter)(atm)/(mol)(K)]

Practice Problem 1. The following table reports the marginal product of the first 16 workers a tomato grower could hire, that is, it tells us how many extra tomatoes each worker could grow. The tomato grower has monthly fixed costs of $50. The monthly wage of each worker is also $50. The tomato grower participates in a perfectly competitive market where there are currently 1000 identical growers. They sell boxes of tomatoes which contain 1500 tomatoes each and currently the market price of these boxes is $200.
