Atrapezoidal channel has a 3m bottom width and a 1: 1 side slope. it carries a discharge of 10 m3 /s at a slope of 12 cm/km. a hydraulic jump forms at an upstream depth of 0.6 m. calculate the specific momentum function, the critical flow depth and the conjugate depth. if you place baffle blocks to induce the hydraulic jump where the upstream depth is 0.4 m and the flow depth downstream of the baffles is 1.2 m, what is the force on the baffles blocks

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.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
