g 1.Water flows in a concrete lined trapezoidal channel on a slope of 0.5%. The channel has a bottom width of 10m, side slopes of 2:1(H:V), and a flowrate of 150m3/s. If the temperature of the water is 20C:(a) Calculate the critical depth.(b) Calculate the normal depth(c) Do you expect the velocity in the channel to prevent sedimentation and growth of vegetation

What precautions should you take to prevent injuries when dealing with heavy loads?

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

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
