1. a one-shell-pass and multiple-of-two tube passes heat exchanger is to be used to cool 12 kg/s of oil with an equal flow rate of water. the heat exchanger area of the heat exchanger is 40 m2. the inlet temperatures of the oil and water are thi = 100 c and tci = 20 c, respectively. the specific heats of the oil and water are 2.09 kj/kg. k and 4.18 kj/kg. k, respectively. the total heat transfer coefficient is controlled by the side and is 1000 w/ m2.k. determine the exit temperature of the oil and water.

Let me look that up brb

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Because its not moving at that time hope u understand
