Lab 1 Recip Engines HW (1)

Short answers please i need question 11&12

Problem Statement A heat engine draws 14 kW of heat from a reservoir at 900 K. The work it produces drives a refrigerator which produces a refrigeration capacity of 12 kW. Both devices reject heat to a reservoir at 300 K. What is the lowest possible temperature of the space cooled by the refrigerator? Answer Table Correct Stage Description Your Answer Answer * 1 Lowest temperature of cold space (K) Due Date Grade (%) Part Weight Attempt Action/Message Type Nov 7, 2024 11:59 pm 0.0 1 1/5 Submit

1.      Based on various gas turbine configurations (i.e turboprop, turbojet, turbofan, turboshaft), indicate which engine type would be most applicable for the following aerospace applications, and why it is the most appropriate i)                   Military application of the Joint Strike Fighter (JSF) ii)                  A short range commercial flight, i.e. Cardiff to Dublin iii)                A hypersonic unmanned aerospace vehicle (UAV) iv)                A long range commercial flight, i.e. London-New York

Petrol vapour and air are drawn into the cylinder, The mixture is then squeezed together, and then exploded by a spark. The explosion pushes down the piston. The exhaust gases are then expelled from the cylinder. pril Use the first law of thermodynamics to analyse the energy changes during the process. At each stage explain what happens to the gas exhaust 0101

##What would an isometric of the oxygen piping system below look like, where PSA GEN = Pressure Swing Adsorption Oxygen Generator (PSA) COMPs = Compressors POMPs = Pumps HEAT = Heat Exchanger PV = Flow Valves ST TANK = Storage Tank VENT = Vent DR = Drains PSV = Pressure Relief Valve In addition, what would be the possible problems that would require flexibility correction by adding expansion joints, spring supports, anchors and brackets?

Hydro Tasmania has initiated the Battery of the Nation (BotN) strategic initiative to investigate and map out future development opportunities for the State of Tasmania to make a bigger contribution to a future National Electricity Market (NEM). The Tarraleah scheme redevelopment pre-feasibility study was undertaken through this initiative, with funding support from ARENA under the Advancing Renewables Program. For this assignment problem you will be using your knowledge of hydro power to: (1) estimate extended specifications for a new power station on the left bank of the Nive River opposite the existing power station; and (2) to reverse engineer specifications for the Pelton turbines currently installed at the Tarraleah power station. The pre-feasibility design team established basic parameters of a new power station to comprise two Francis turbines with a design flow of 20 m³/s (total 40 m³/s), a net head of 305 m and an installed capacity of ~57 MW (total 113 MW). The Tarraleah…
