Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 …
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experime…

Chapter 4.1, Problem 58E

Fluctuation in the Solar Constant The solar constant S is the amount of energy per unit area that reaches Earth’s atmosphere from the sun. It is equal to 1367 watts per m2 but varies slightly throughout the seasons. This fluctuation Δ S

in S can be calculated using the formula

Δ S = 0.034 S sin [ 2 π ( 82.5 − N ) 365.25 ] .

In this formula. N is the day number covering a four-year period, where N = 1 corresponds to January 1 of a leap year and N = 1461 corresponds to December 31 of the fourth year. (Source: Winter. C.. R. Sizmann. and L. L.Vant-Hull, Editors. Solar Power Plants, Springer-Verlag.)

(a) Calculate Δ S for N = 80. which is the spring equinox in the first year.

(b) Calculate Δ S for N = 1268, which is the summer solstice in the fourth year.

(c) What is the maximum value of Δ S

?

(d) Find a value for N where Δ S is equal to 0.
