Design a V-belt drive. Specify the belt size, the sheave sizes, the number of belts, the actual output speed, and the center distance. Please, show step-by-step process using tables/charts/figures from textbook. Driver type: AC Motor (Normal torque) Driven machine: fan Service: 11 h/day Input speed: 1750 rpm Input power: 5 hp Nominal output speed: 725 rpm

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

On a average work day more than work place firs are reorted

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.
