In a crash test, a 2500 kg car hits a barrel

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

What causes the development of most clouds and precipitation in the atmosphere?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
