Since it is 50 mm, it is kept at 100 oC through a thin-walled tube. In the first weather condition 25 oC. And it flows at a speed of 30 m/s while traveling globally. Advanced in the second weather It flows in the overalls at a temperature of 25 °C and a speed of 30 m/s. Heat flux in both pipes Please hand and interpret through the given names.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
