A swimming pool is 20 ft wide and 40 ft long and its bottom is an inclined plane, the shallow end having a depth of 3 ft and the deep end, 9 ft. If the pool is full of water, estimate the hydro static force on the deep end.

A swimming pool 20 m long and 8 m wide has a sloping plane bottom so that the depth of the pool is 1 m at one end and 3 m at the other end. Find the total force exerted on the bottom if the pool is full of water.

A swimming pool is 20 ft wide and 40 ft long and its bottom is an inclined plane, the shallow end having a depth of 3 ft and the deep end, 9 ft. If the pool is full of water, estimate the hydrostatic force on the bottom of the pool.

Water is flowing at the rate of $50 \mathrm{~m}^3 / \mathrm{min}$ from a shallow concrete conical reservoir (vertex down) of base radius $45 \mathrm{~m}$ and height $6 \mathrm{~m}$. How fast is the radius of the water's surface changing then? Answer in centimeters per minute.

A swimming pool is 20 feet wide and 40 feet long and its bottom is an inclined plane, the shallow end having a depth of 3 feet and the deep end, 9 feet. If the pool is full of water, find the hydrostatic force on the deep end.

A device commonly used to measure the ongoing level of a behavior is a c_________ r_______. On this device, a flat line indicates (no/slow/fast) responding, while a steep line indicates ________ responding and a shallow line means _______ responding.

To what do internal and external flow refer in forced convection cooling? Give an example of a forced-air-cooled electronic system that involves both types of flow.

A swimming pool is 20 ft wide and 40 ft long and its bottom is an inclined plane, the shallow end having a depth of 3 ft and the deep end, 9 ft. If the pool is full of water, estimate the hydrostatic force on one of the sides.

A timber beam having a rectangular cross section is used as a simply supported beam with a span of $8\ \mathrm{ft}$. It supports two equal concentrated loads of $P=6000\ \mathrm{lb}$, so there is a load $2\ \mathrm{ft}$ from each end (loads at quarter points). The allowable stress in bending is $800\ \mathrm{psi}$, in shear parallel to the grain $80 \mathrm{psi}$, and bearing perpendicular to the grain of the wood 210 psi. Determine (a) the beam required to safely support the loads (neglect weight of beam), and (b) the bearing plate sizes required at the supports and concentrated loads.

Concentrated acetic acid is diluted with water to make a $5 \%$ acetic acid solution, similar to the vinegar used on French fries. Explain how you know which substance is the solvent and which is the solute.

A digital flow meter operates by emitting a pulse for each unit volume of fluid flowing through it. The particular flow meter of interest has a unit volume of $50 \mathrm{~cm}^3$ per pulse. In a certain process control application, the flow meter emitted 3,688 pulses during a period of $2.5 \mathrm{~min}$. Determine (a) the total volume of fluid that flowed through the meter and (b) the flow rate of fluid flow. (c) What is the pulse frequency (Hz) corresponding to a flow rate of $60,000 \mathrm{~cm}^3 / \mathrm{min} ?$

Treatment of 3-buten-2-ol with concentrated hydrochloric acid gives a mixture of two products, 3-chloro-1butene and 1-chloro-2-butene. Write a reaction mechanism that explains how both products are formed.
