A large refrigeration plant is to be maintained at $-15^{\circ} \mathrm{C},$ and it requires refrigeration at a rate of 100 kW. The condenser of the plant is to be cooled by liquid water, which experiences a temperature rise of $8^{\circ} \mathrm{C}$ as it flows over the coils of the condenser. Assuming the plant operates on the ideal vapor-compression cycle using refrigerant-134a between the pressure limits of 120 and 700 kPa, determine (a) the mass flow rate of the refrigerant, (b) the power input to the compressor, and (c) the mass flow rate of the cooling water.

A farmer has three hundred acres of arable land on which she wants to plant cauliflower and cabbage. The farmer has $\$ 17,500$ available for planting and $\$ 12,000$ for fertilizer. Planting 1 acre of cauliflower costs $\$ 70$, and planting 1 acre of cabbage costs $\$ 35$. Fertilizer costs $\$ 25$ for 1 acre of cauliflower and $\$ 55$ for 1 acre of cabbage.

(a) Find a system of inequalities that describes the number of acres of each crop that the farmer can plant with the available resources. Graph the feasible region.

(b) Can the farmer plant one hundred fifty-five acres of cauliflower and one hundred fifteen acres of cabbage?

(c) Can the farmer plant one hundred fifteen acres of cauliflower and one hundred seventy-five acres of cabbage?

You are handed a mystery pea plant with tall stems and axial flowers and asked to determine its genotype as quickly as possible. You know that the allele for tall stems (7) is dominant to that for dwarf stems (t) and that the allele for axial flowers (A) is dominant to that for terminal flowers (a). Identify ALL the possible genotypes for your mystery plant.

Where does most of the photosynthesis occur in a plant?

A stomata

B guard cells

C vascular cambium

D mesophyll tissue

The water flow meter at the Westwood water plant is malfunctioning. The plant superintendent tells you the four dual-media filters (each $5.00 \mathrm{m} \times 10.0 \mathrm{m}$) are loaded at a velocity of 280 $\mathbf{m} \cdot \mathrm{day}^{-1}.$ What is the flow rate through the filters (in $m^{3} \cdot s^{-1}$)?

What does a plant need that makes it necessary for seed germination to start with the emergence of a root rather than a shoot?

The following questions are unrelated except that they all apply to plant assets and intangible assets:

1. The manager of Wired Connections Inc. regularly buys plant assets and debits the cost to Repairs and Maintenance Expense. Why would he do that, since he knows this action violates GAAP?

2. The manager of Alpine Homes debits the cost of repairs and maintenance of plant assets to Plant and Equipment. Why would she do that, since she knows she is violating GAAP?

3. It has been suggested that because many intangible assets have no value except to the company that owns them, they should be valued at $1.00 or zero on the balance sheet. Many accountants disagree with this view. Which view do you support? Why?

Which tool could help you see a plant cell? a. a filter b. a microscope c. a microwave d. an electromagnet

Name at least six types of products or fabrications that would be suitable for the engineer or architect to call for inspection at the manufacturing or fabrication plant.

You have three plants—one $C_3$, one $C_4$, and one CAM plant. You also have a pH meter and a microscope. Describe how you could use only your pH meter and microscope (with the necessary supplies that go with each instrument) to identify each plant as $C_3$, $C_4$, or CAM.

PhotoTech, Inc., a manufacturer of rechargeable batteries for digital cameras, signed a contract with a digital photography company to produce three models of lithium-ion battery packs for a new line of digital cameras. The contract calls for the following:

$$\begin{array}{cc} \text { Battery Pack } & \text { Production Quantity } \\ \text { PT-100 } & 200,000 \\ \text { PT-200 } & 100,000 \\ \text { PT-300 } & 150,000 \end{array}$$

PhotoTech can manufacture the battery packs at manufacturing plants located in the Philippines and Mexico. The unit cost of the battery packs differs at the two plants because of differences in production equipment and wage rates. The unit costs for each battery pack at each manufacturing plant are as follows:

$$\begin{array}{ccc} \text { Product } & \text { Philippines } & \text { Mexico } \\ \text { PT-100 } & \$ 0.95 & \$ 0.98 \\ \text { PT-200 } & \$ 0.98 & \$ 1.06 \\ \text { PT-300 } & \$ 1.34 & \$ 1.15 \end{array}$$

The PT-100 and PT-200 battery packs are produced using similar production equipment available at both plants. However, each plant has a limited capacity for the total number of PT-100 and PT-200 battery packs produced. The combined PT-100 and PT-200 production capacities are 175,000 units at the Philippines plant and 160,000 units at the Mexico plant. The PT-300 production capacities are 75,000 units at the Philippines plant and 100,000 units at the Mexico plant. The cost of shipping from the Philippines plant is $0.18 per unit, and the cost of shipping from the Mexico plant is$0.10 per unit.

a. Develop a linear program that PhotoTech can use to determine how many units of each battery pack to produce at each plant to minimize the total production and shipping cost associated with the new contract.

Calculate the amount of $\mathrm{CaCO_3}$ (in grams) that would be required to react with $50.6 ~g$ of $\mathrm{SO_2}$ emitted by a power plant.
