(a) Water flows through the nozzle of a garden hose. Find an expression for m in terms of line pressure P1, ambient pressure P2, inside hose diameter D1, and nozzle outlet diameter D2. Assume steady flow, and isothermal, adiabatic operation. For liquid water modeled as an incompressible fluid, H2 H1 = (P2 P1)/ for constant temperature. (b) In fact, the flow cannot be truly isothermal: we expect T2 > T1, owing to fluid friction. Hence, H2 H1 = C(T2 T1) + (P2 P1)/, where C is the specific heat of water. Directionally, how would inclusion of the temperature change affect the value of m as found in part (a)?
