Air from a workspace enters an air conditioner unit at 308C dry bulb and 208C wet bulb. The air leaves the air conditioner and returns to the space at 208C dry-bulb and 6.58C dew-point temperature. If there is any, the condensate leaves the air conditioner at the temperature of the air leaving the cooling coils. The volume flow rate of the air returned to the workspace is 800 m3 /min. Atmospheric pressure is 101 kPa. Determine the heat transfer rate from the air, in kW, and the mass flow rate of condensate water, if any, in kg/h.
Lecture 4/11/16 Marxism: Lenin and Imperialism th • 19 Century capitalism was doomed o The logic of Internal Contradictions § Capitalism sows seeds of own destruction o 1.) Production Problems § over-production (consumers = working class, if under-paid they will not to be able to consume. Over produced/under consumed= profits plunge=lay workers off.) ú Results: Saturated markets, falling profit • Imperialism: capitalism saves itself via colonialism o Cheaper raw material o Cheaper labor o New markets Marxism and IPE (International Political Economy) • All about economic exploitation • Prosperity requires that someone remains poor o Economic relations benefit the north (the center) o The south (the periphery) kept down § à source of cheap labor, raw materials, and markets o most trade is North-North and North-South: little South-South § north at center of global trade • View of IGO’s o IMF, WB, WTO, are tools of oppression Solution: become self sufficient, the south needs to exit the capitalist trading system and create its own trading zone Lecture 4.13.16 Dependency Theory: Goal: explain underdevelopment of the periphery • Liberal policies advocate development though… o Export-oriented growth o Problem: declining terms of trade § Type, supply, worth of core vs. periphery products ú Periphery is dependent on core, not equal partners in global trade Outcomes: • Not engage in trade with North o Underdevelopment (ex. Chad) • Engage in trade with North o Dependent development (ex. Brazil) Dependency Theory Policy Recommendation: • ISI- import substitution industrialization (industrialize at home instead of importing) • Why does this not work well Can’t produce good products for cheap enough to sustain Economic Interdependence • Economies dependent on one another (U.S. and China) • Reflects liberal view of IPE • Lower likelihood of fighting between economically interdependent countries • Basic Reasons: o hurting their economy hurts your own (economies intertwined) o fighting interrupts trade with third world countries à lower profits (conflict scares off partners) o Decision making is constrained when in economically interdependent situation o Erosion of sovereignty § Realists hate economic interdependence for this reason __________________________________________________ Recitation 4/13/16 Trade and Development • Trade Politics o Generally accepted that trade gives more stuff to countries overall- comparative advantage o Why might countries not want free trade § Domestic politics or mercantilism o Mercantilism: § How should states behave economically according to mercantilism --- gain the most money so you can gain the most power § Associated with Realism o Liberalism and Trade § According to liberalism, would countries prefer high or low levels of protectionism § Low protectionism (more trade)- absolute gains for country as a whole o Avoiding protectionism § Ideally a country would want to be the only one implementing protectionism ú Get gains from trade/exports ú Protect domestic industry § International trade agreements/institutions ú NAFTA, WTO ú Get everyone to agree to free trade ú Institutions can investigate violations o IPE and Development § Which of the following trade patterns do we see ú South-South –Not much ú North-North –high technology ú North-South –often o Dependency Theory § Accepts that comparative advantage exists § But, only a one time benefit ú By specializing in producing low end good, you can’t learn how to produce high end good § Getting stuck producing low end good outweighed the advantages of trade o Import Substitution Industrialization § Problem: trade means specializing in producing low end goods § Answer: stop buying high end goods from the north, and learn to make them yourself § Two Parts: ú Protectionism ú State-led investment/subsidies o ISI Problems § Run out of money ú Debt crises § No competition ú Goods are low quality § Corruption § May make price of high end good higher for domestic consumers
