Calculate the pressure at an ocean depth of 1480m. The acceleration of gravity is 9.8 m/s2 , atmospheric pressure is 1.01 � 105 Pa , and the density of the seawater is 1024 kg/m3.

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.
