You are tasked with evaluating the stirring tank in a chemical plant. The temperature of the inlet stream of the fluid entering the tank is at 300K, has a specific heat capacity of 10 J/(kg*K) and a flow rate of 1 kg/s. The stirrer adds 10 kW power to the system, while an internal cooling coil in the tank removes heat at a rate of 5000 J/s. The line surrounding the pipe of the outlet stream of the fluid exiting the tank will catch on fire if it reaches a temperature of above 500K. Will the liner catch fire?

A pump carries water at a temperature of 30 ° C from one tank
(A) to another (B). The diameter of the pipe leaving tank A and
reaching the pump is 4 inches. The diameter of the pipe leaving the
pump and reaching tank B is 3 inches. The pump motor increases the
fluid pressure by 3 kgf / cm2 (ΔP), and generates a power per unit
of mass of 300 J / kg. Calculate the height difference (ΔZ) between...
