1) In the figure below, applying Bernoulli's theorem to an ideal and incompressible fluid in a stationary and adiabatic regime, obtain the mass flow, as a function of the properties: A1; A2; h and acceleration due to gravity (g). Repeat and obtain the mass flow, depending on the properties: A1; A2; P1; P2 and density (ρ).

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

Aweight lifter raises a 1600 n barbell to a height of 2.0 meters. how much work was done? w = fd a) 30 joules b) 3000 joules c) 320 joules d) 3200 joules

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
