Water goes through a pipe with a velocity of 10 m/s and the radius of the pipe is 0.25 m. Calculate the volumetric flow rate and the mass flow rate
of water going through the pipe. Consider the specific volume of water to
be 0.001 kg/m3 and the gravitational acceleration (8) to be 10 m/s

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.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
