I NEED URGENT HELP I have a group project due tomorrow but my partners aren’t doing ANYTHING so it’s up to me to make something so we don’t fail. I need an example of a problem In day to day life that I can solve with engineering

Fluids at rest possess no flow energy. a)- true b)- false

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
