A long concrete beam is to undergo a thermal test to determine its loss of strength in the event of a building lire. The beam cross section is triangular as shown in the sketch. Initially, the beam is at a uniform temperature of 20 °C. At the start of the test, one of the short faces and the long face are exposed to hot gases at 400 °C through a heat transfer coefficient of le W/(mz K) and the remaining short. face is adiabatic. Produce a graph showing the highest and lowest temperatures in the beam as a function of time for the first 1 hour of exposure. For the concrete properties, use k - 0.5 Va(mK) and a = 5 x 10-7 m2.1s. Use a node spacing of 4 cm. and use an explicit difference scheme.
the load on a 2 inch diameter hydraulic cylinder increases from 10000lb to 15000lb. due to compressibility of oil the
Given a simple Rankine cycle with temperature and pressure from the boiler of 580°C, 10 MPa and a condenser pressure of 6 kPa, with the condensate exiting as saturated liquid. The isentropic efficiencies of the turbine and pump are 85% and 82% respec..
An air-standard Otto cycle has a compression ratio of 6. At the beginning of compression, the pressure is 100 kPa and the temperature is 300 K. During the heating process, the temperature is raised to 2500 K. Assume that the cold air-standard assumpt..
Suppose you are working for a start-up company that is designing a very new and innovative product. Does the client–user–designer model still apply? Who is your client in this case? Since you don’t have any customers yet, who are the users and how ca..
