Avery thick concrete wall 2=8x10 m/s and k = 0.8 w/mk initially at 60° suddenly exposed to a cobled stream da=5% ond h=10 wlme k obtain steady state temperatur distribution at a depth of 6 cm from surface at end of 10 min

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
