ME 432: Applied Thermodynamics Assignment 1 1. A steam turbine operates at steady state with inlet conditions of P1 = 5 bar, T1 = 320 o C. Steam leaves the turbine at P2 = 1 bar and T1 = 180 o C. There is no significant heat transfer between the turbine and its surroundings, and kinetic and potential energy changes between inlet and exit are negligible. a. Calculate power output (per unit mass of steam flowing) of the turbine. b. Calculate the isentropic efficiency of the turbine (ηs ) and show the states

Cloud computing is a new area of research currently being studied [1]. Basically it’s not a technology it’s a computing model. We can also define Cloud computing as both the applications delivered as services over the internet and the hardware and system software in the data centers that provide those services [2]. OR type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified

Question (a) Every firm goal to maximize its profit. Profit is equal to total revenue (TR) minus total cost (TC), the left over money is called profit. So, the higher the profit, the more the money a company has. Diagram 1 “Based on the Diagram 1 above, the quantity they should produce at the point where marginal revenue equal to marginal cost, to help the company get the profit-maximizing, which also known as normal profit.” (Riley, 2015). Meanwhile, the revenue from selling is equal to the

and is calculated by the formula (Q2−Q1)(P2+P1) (Q2+Q1)(P2−P1) where Q1= Initial quantity Q2=Final quantity P1=Initial price P2=Final price. If a product or service is elastic, where the result of the formula is greater than 1meaning quantity demanded is extremely sensitive, a company should lower prices, this will increase demand and total revenue will increase. If the product or service is inelastic, where the result of the formula is less than 1 meaning quantity demanded is not sensitive

Actual Compressor Calculations 1. Use guidelines for ideal gas turbomachinery to calculate ideal specific work and power. 2. Calculate volume flow rate in cubic feet per minute at the compressor inlet 3. Use the Brake Horsepower for a Generic Centrifugal Compressor graph to determine the basic brake horsepower. 4. Calculate the actual power by multiplying the basic brake horsepower by the ratio of the inlet pressure (in psig) to 14.5. This will give actual power in units of horsepower. You may wish
