A blood warmer is to be used during the transfusion of blood to a patient. This device is to heat blood taken from the blood bank at 10°C to 37°C at a flow rate of 200 ml/min. The blood passes through tubing of length 2 m, with a rectangular cross section 6.4 mm×1.6 mm. At what rate must heat be added to the blood to accomplish the required temperature increase? If the fluid originates from a large tank with nearly zero velocity and flows vertically downward for its 2-m length, estimate the magnitudes of kinetic and potential energy changes. Assume the blood's properties are similar to those of water
Given a simple Rankine cycle with temperature and pressure from the boiler of 580°C, 10 MPa and a condenser pressure of 6 kPa, with the condensate exiting as saturated liquid. The isentropic efficiencies of the turbine and pump are 85% and 82% respec..

Helium is to be compressed from 120kPa and 315K to 700kPa and 450K. A heat loss of 20kJ/kg occurs during the compression process. Neglecting kinetic energy changes, determine the power input required for a mass flow rate of 78kg/min. Round to nearest..
