Complete Question
Water is flowing in a trapezoidal channel at a rate of Q=20m³/s . The critical depth y for such a channel must satisfy the equation:
0 = 1 − Q² / gA³c . B Where g= 9.81m /s² and Ac = the cross-section area can be related to depth y by B = 3+y and Ac = 3y+y²/2. Solve for the critical depth using (a). the graphical method,
Answer:
Given the equation,
0 = 1 − Q² / gA³c. B
Now substituting the given value g= 9.81m /s² , Q =20m³/s, B = 3+y, and Ac = 3y+y²/2,
We get:
0 = 1 - 20² / (9.81) ( 3y + y²/2)³ (3+y)
Hence we choose f(y) = 1 - 40.7747 / (3y + y²/2)³ . (3 + y) and solve for f(y) = 0
Therefore,
To solve using a graph, we take twelve sample points ( starting at y = 0.25 in step of 0.25m and plot a graph using MS- Excel. Kindly find the graph below.
2) As evident from the sample point and the graph function f(y) gets close to zero at y = 1.5, hence the root of f(y) = 0 is Xr = 1.5
Answer: $45,000
Explanation:
Last In First Out (LIFO) is an inventory valuation and management method that works by selling the most recent inventory to come into the business as opposed to the earlier ones.
In the above, the most recent Inventory to come in is the 5,000 units bought at $10 each.
The 4,500 units sold will therefore come from there.
Cost of Goods Sold = Units Sold * Purchase Price
= 4,500 * $10
= $45,000
Answer:
Sunderland Company should increase debt investment by $2,685.00
Explanation:
Sunderland Company needs to increase its debt investments account for Scott Company bonds with the difference between effective interest earned on July 1 2021 minus the actual coupon interest received as shown below:
The actual interest revenue earned = $1122375*12%
=$ 134,685.00
The coupon interest received=$1,200,000*11%
=$ 132,000.00
In a nutshell,the investment in bonds earned interest of $134,685 but only $132,000 was received in cash,hence the difference of $2,685 is added to the bonds investment figure($134,685-$132,000)
Answer:
Overhead costs
Explanation:
When high overhead costs are recognised before project starts there will be a need to manage them. Since overhead cost increase as duration of project increases, reduction in project duration will go a long way in reducing cost incurred.
Overhead costs can include wages, rent, utility bills, maintenance costs and so on. They can also be reduced when costs that are not adding value is recognised.
