Determine the pressure exerted on the surface of a submarine cruising 225 ft below the free surface of the sea. Assume that the barometric pressure is 14.7 psia and the specific gravity of seawater is 1.03.

The basic barometer can be used to measure the height of a building. If the barometric readings at the top and at the bottom of a building are 730 and 755 mmHg, respectively, determine the height of the building. Assume an average air density of $1.18 kg/m^3.$

The vacuum pressure of a condenser is given to be 80 kPa. If the atmospheric pressure is 98 kPa, what is the gage pressure and absolute pressure in kPa, $kN/m^2, lbf/in^2,$ psi, and mmHg.

This problem will show why steady-state probabilities are sometimes referred to as stationary probabilities. Let π1, π2, …, πs be the steady-state probabilities for an ergodic chain with transition matrix P. Also suppose that with probability πi, the Markov chain begins in state i. a. What is the probability that after one transition, the system will be in state i? b. For any value of n(n = 1, 2, …), what is the probability that a Markov chain will be in state i after n transitions? c. Why are steady-state probabilities sometimes called stationary probabilities?

Mount Everest’s summit is $8850~\text{m}$ $(29,035~\text{ft})$ above sea level. What is the barometric pressure there according to the standard atmosphere?

Determine the pressure exerted on a diver at 20 m below the free surface of the sea. Assume a barometric pressure of 101 kPa and a specific gravity of 1.03 for seawater.

Determine the limit of the function describing the atmospheric pressure on a plane as it descends from $32,000$ feet to land at Honolulu, located at sea level. (The atmospheric pressure at sea level is $14.7$ pounds per square inch.)

An air-conditioning system required a 35-m-long section of 15-cm-diameter ductwork to be laid underwater. Determine the upward force the water will exert on the duct. Take the densities of air and water to be 1.3 kg/m^3 and 1000 kg/m^3, respectively.

When calculating the barometric pressure for a city located $200$ meters above sea level, would you (add or subtract) units to its barometric reading in order to correct its pressure to sea level? You would _____________ units to the barometric reading.

The water in a 25-m-deep reservoir is kept inside by a 90-m-wide wall whose cross section is an equilateral triangle, as shown in the figure. Find (a) the total force (hydrostatic $+$ atmospheric) acting on the inner surface of the wall and its line of action and (b) the magnitude of the horizontal component of this force. Take $P_{\mathrm{am}}=100\ \mathrm{kPa}$.

The basic barometer can be used to measure the height of a building. If the barometric readings at the top and at the bottom of a building are 675 and 695 mmHg, respectively, determine the height of the building. Take the densities of air and mercury to be 1.18 kg/m^3 and 13,600 kg/m^3, respectively.

A pressure gage connected to a tank reads 50 psi at a location where the barometric reading is 29.1 in Hg. Determine the absolute pressure in the tanlk. Take $\rho_{\text{Hg}}$= 848.4 lbm/ft^3. Answer: 64.3 psia

A manometer containing oil ($\rho$= 850 kg/m^3) is attached to a tank filled with air. If the oil-level difference between the two columns is 80 cm and the atmospheric pressure is 98 kPa, determine the absolute pressure of the air in the tank. Answer: 105 kPa
