The deepest part in the ocean is the challenger deep within the mariana trench, which has a maximum depth of around 11,000 m. this question will look to estimate the pressure at this depth in the ocean. (a) (2 points) assuming that the salt water in the ocean has a constant density of 1030 kg/m", compute the pressure at this deepest point in the ocean. use gage (relative) pressure, with p= 0 pa at the surface. (b) (4 points) while liquids are approximately incompressible, at such depths density variations can be noticeable. assume that the density of the water varies with depth by the equation p- po ppo cape p= po exp where po and po are the density and pressure at the surface, and ey = 2.3 x 10° n/m² is the modulus of elasticity of water. using the differential form of the hydrostatic pressure equation dp da = -29, determine the pressure at the deepest point of the challenger deep. as- sume that po = 1030 kg/m². how does this compare to your answer for part (a)?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
