A 20-acre watershed located in Lakeville, MA with land use information below is given:Land use (%)Soil group Descriptions 4025 20 15BC DO Residential(average lot size ¼acre)Open space (in good condition) Commercial and business Industrial Estimate (a) the weighted curve number for this watershed for normal moisture conditions, (b) the initial abstractions in "inches", (c) the rainfall depth for a 30-min 5-yr storm for the site location in "inches", and (d) the direct runoff from the site in "ft3" and "acre-ft" for the above specified storm

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
