What lot sizes would the supplier of carpet prefer to make for types 1, 2, 3, and 4?

/in /by

Suppose you are the supplier of the Cover-up Drapery Company described in problem 13. It costs $2000 each time you change over your fabric-producing machine from one type to another (1, 2, 3, or 4). Assume that your carrying cost is 30 percent and the other data are as given in problem 13. a. What lot sizes would the supplier of carpet prefer to make for types 1, 2, 3, and 4? b. How would you reconcile the lot sizes that the supplier would like to produce and those that the Cover-up Drapery Company would like to buy? Describe several ways in which these two differing lot sizes can be reconciled.

Assignment 3

Econ 305 assignment

The assignment is out of 20. If you work with others, please indicate their names in the top right-hand corner of your assignment (you will not be penalized). In any event, write up the work on your own. Copying/paraphrasing will be considered cheating.

(20 marks) The Bank of Canada makes an Advance to RBC of $300 million.

(a) (2 marks) Show the changes to the balance sheets of both RBC and the Bank of Canada. Consider the following deposit expansion process.

(i) RBC lends the $300 million to Research in Motion Ltd. (RIM) by issuing a chequable deposit. RIM withdraws the money and spends it.

(ii) The money RIM spends is deposited the next firm at TD Trust Canada.

(iii) TD Trust Canada’s loan goes to BRIM Ltd.; BRIM spends it and proceeds are deposited by the next firm at BMO.

(b) (5 marks) Show the changes in two stages to the balance sheets of both RBC and TD Trust Canada. If TD and BMO wants to maintain a 10% reserve ratio how much will they lend out? Show the changes to TD and BMO’s balance sheets in two steps.

(c) (5 marks) Recreate Table 15.1 (in the Chapter 15 slides) but for this scenario. Assume that every bank wishes to hold 10% of deposits in reserve.

The money multiplier process is analyzed in the standard way where banks maintain a large positive required reserve ratio (e.g. 10% in this exercise). This analysis fits the US. However, in some countries there is no required reserve ratio! Suppose that all excess reserves are lent so that the desired reserves would be zero. That is, rD = 0!

(d) (8 marks) Repeat (b)[ii-iii] – (c), assuming all excess reserves are lent. What is the implied money multiplier? Name two considerations/extensions which would give a more reasonable answer.

Assuming a laminar boundary layer along the diffuser wall, calculate the location of flow separation in the diffuser.

/in /by

For the conditions of Prob. 4.56, but assuming a turbulent boundary layer, an approximate criterion for the separation point is x. = 506(}-1 ..,., where x. is in m. Calculate the location of flow separation for a turbulent boundary layer along the diffuser wall. Prob. 4.56 The diffuser of a wind tunnel or at the inlet of an air-breathing jet engine is designed to slow the flow. Consequently, from Euler’s equation, Eq. (4.8) in the text, the pressure always increases with distance along the diffuser. Hence, in terms of the discussion in Sec. 4.20, the flow in the diffuser is experiencing an adverse pressure gradient, which encourages: the boundary layer to separate from the wall of the diffuser, thus resulting in a loss of total pressure and reducing the aerodynamic efficiency of the diffuser. For the wind tunnel and flow conditions described in Probs. 4.49-4. 55, a criterion that predicts approximately the location along the wall of the diffuser where a laminar boundary will separate is given by x. = 183(/dx)-1 .,. where x. is the separation location in m and (dp/dx).,. is the average of the pressure gradients in N/m3 at the entrance and exit of the diffuser assuming no flow separation. Assuming a laminar boundary layer along the diffuser wall, calculate the location of flow separation in the diffuser.
