Calculate the single payment factor and the present value factor with the above data with the table and formula. Draw the flow chart.
Explanation:
Answer:
t=2.025 inches
Explanation:
Given that
P = 400 Psi
Yield stress ,σ = 80 ksi
Diameter ,d= 45 ft
We know that
1 ft = 12 inches
d= 540 inches
Factor of safety ,K= 3
The required thickness given as

t=thickness


t=2.025 inches
Therefore thickness will be 2.025 inches.
Answer:
The option that is best described as a way engineers can test and investigate how things should be under certain circumstances is;
Explanation:
Modeling is a tool an engineer can use for the physical representation of a system that will facilitate the definition, testing and analysis, communication, data generation, data verification and data validation of given concepts
Models also aid in setting specifications, supporting designs, and verification of a given system
Therefore, with modeling engineers can investigate the behavior of systems under given environmental conditions.
Answer:
Explained below
Explanation:
The isohyetal method is one used in estimating Rainfall whereby the mean precipitation across an area is gotten by drawing lines that have equal precipitation. This is done by the use of topographic and other data to yield reliable estimates.
Whereas, the arithmetic method is used to calculate true precipitation by the way of getting the arithmetic mean of all the points or arial measurements that will be considered in the analysis.
