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:
$4,000
Explanation:
The computation of amount of Virginia's casualty loss is shown below:-
If property is personal property or is not absolutely destroyed, then the amount of loss of casualty is the lower of:
1. The adjusted asset base, or
2. Reducing the fair market value of the property as a result of the incident
But loss of casualty, should be decreased by any salvage value by any insurance or even other reimbursement that you obtain or consider.
Basis = $14,000
Decrease in fair market value = $10,000
Lower of above = $10,000
From insurance company the Reimbursement is = 6000
So, the Loss of Casualty = $10,000 - $6,000
= $4,000
Answer:
Economic profit for the year is
Explanation:
The accounting profit will be Revenue - expenses (150,000-35,000) $ 115,000. However this problem requires us to calculate economic profit. Economic profit is different from accounting profit. While calculating it opportunity costs also become part of expenses as implicit costs. Detail calculation is given below.
Economic profit = 150,000 -35,000-20,000 = $ 95,000
Answer: Sunk cost
Explanation:
Sunk cost also sometimes referred to as past cost is a cost that has already been spent by an individual or firm and cannot be recovered.
From the question, if $500 was spent last week in fixing the transmission in a car and the brakes are now acting up, and one has to decide qwhether to fix them or trade the car in for a newer model.
The amount spent on the brake situation in this case is a sunk cost as it has already been incurred and nothing can be done about it anymore.
