A submerged steel-reinforced concrete block, with a specific weight of 164 lbf/ft3, is needed to keep the 2 foot-wide gate in a closed position when the depth, H, of the liquid is 4.4 feet. The block is connected to the gate by a cable and system of pulleys. The specific gravity of the liquid is 0.98. The gate pivots about point A. To 3 significant digits, the minimum volume of the submerged concrete block is (if the third digit is a zero, make sure you include it)

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.

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
