Question
Chapter 7, Problem 7.1P
To determine
The difference between pyrolysis and gasification.
Expert Solution & Answer
Explanation of Solution
Pyrolysis is the process in which combustion takes place in the absence of oxygen. It is the thermal method of decomposition at high temperature in a nonreactive environment. This method is mainly used for decomposition of organic waste. Generally, the organic substance is volatile in nature so, during pyrolysis, they leave the solid material and gets evaporated at an elevated temperature which is enriching in carbon and charcoal.
Gasification is the process in which the organic matter is decomposed in the presence of oxygen at elevated temperature. In this process, organic matter is disintegrated into hydrogen, carbon monoxide, and carbon dioxide. The product of this process is used as a renewable source of energy.

(20 customer per hour) and the service rate (30 customers per hour) random variables are Markovian.
(a) What is the mean queue length? [3 pts]
(b) Percentage of Idle time of the server? [3 pts]
(c) Average number in the queue? [3 pts]
(d) Average number in the system? [3 pts]

A toll booth on the Thruway experiences an average inter-arrival time of 3 minutes between each
vehicle. As an operator, you want to have a mean queue length of at most 2 vehicles. What mean
service rate (per hour) will the toll booth need to provide?
A freeway is to be designed at a location on level terrain for an annual average daily traffic (AADT)
of 45,000 vehicles per day. For a conversion of AADT to an annual hourly volume, assume that the
K-factor is 0.10 (i.e., the 30th highest hourly volume of the year). In addition, 55% of the peak-hour
traffic volume is expected to travel in the peak direction (D = 0.55). This freeway segment will be
for regular commuters. Other estimates include: PHF of 0.95, free-flow speed of 65 mph, and 20%
trucks of the traffic stream. In order to determine the number of lanes required to provide at least
LOS C, answer the following questions.
(a) Determine Free Flow Speed (FFS) [4 pts]
(b) Find the directional design-hour volume (DDHV) [4 pts]
(c) Find fHv [4 pts]
(d) Determine the number of lanes required. [4 pts]
(e) Check the expected LOS for 2-directional lanes on this freeway segment. [4 pts]

In order to mitigate against the problem, authorities have decided to construct a flood protection bund (Dyke). Figure 1 is a cross section of a 300m long proposed dyke; together with its foundation (key). Survey data for the proposed site of the dyke are presented in Table 1. Table 2 provides swelling and shrinkage factors for the fill material that has been proposed. The dyke dimensions that are given are for a compacted fill. (1) Assume you are in the design office, use both the Simpson Rule and Trapezoidal Rule to compute the total volume of earthworks required. (Assume both the dyke and the key will use the same material). (2) If you are a Contractor, how many days will it take to finish hauling the computed earthworks using 3 tippers of 12m³ each?
