Find an expression for the pressure variation in the ocean assuming po = 1030 kg/m³ for salt water using thebulk modulus to be 2100 MPa (see the solution to Solved Problem 2.1). Estimate the pressure at 2000 musing (a) the expression developed and (b) a constant density of 1030 kg/m³. (c) Calculate the percent errorin (b) assuming (a) is the accurate value.2.132.14From about 12 to 20 km, the temperature in the stratosphere is constant at 217 K. Assuming the pressureat 12 km to be 19.4 kPa, use Eq. (2.13) to approximate the pressure at 20 km. Calculate the error usingTable C.3 in App. C to obtain the more accurate value. 2.1Derive an expression for the density variation in a liquid assuming a constant bulk modulus and aconstant temperature.The density varies in a liquid according to Eq. (1.13), B= p Ap/Ap[t. Over a small pressure difference,this can be written as, using Eq. (2.9),Bdp ==dp = pg dh ordpВAssuming a constant value for B, set up an integration:dpdhIntegrating gives the increase in density asghor11Pop =1- gpoh/B%3DPoBThis could be used with dp = pg dh to provide the pressure variation in the ocean.

The Ekman number, Ek, arises in geophysical fluid dynamics. It is dimensionless parameter combining seawater density ρ, a characteristic length L, Seawater viscosity μ, and the Coriolis frequency Ωsinφ, where Ω is the rotation rate of the earth and φ is the latitude angle. Determine the correct form of Ek if the viscosity is in the numerator.

The effect of surface tension on the mass of a falling drop is studied. According to Raleigh for non-viscous flow the mass of a drop, ma, is a function of the surface tension, σ, the diameter of the droplet, d, the gravity, g, and the flow density, p. ma = f(d,g,p,σ) Find the relevant dimensionless numbers.
Consider a water tank that is being filled with rainfall at the top and is drained through a small hole atthe bottom. The change in volume can be modelled by considering the amount of water entering andleaving the tank (per unit of time) as followsdVdt= fin − fout.Here volume of water in the tank V is in litres, flow rate in fin is in litres per hour, flow rate out fout isin litres per hour and time t is in hours. Initially, the tank contains 50L of water: V (0) = 50.(a) Assume the rainfall throughout the day is getting heavier, such that, fin(t) = 10 + t andthat the tank is losing 10% of its volume of water per hour, such that, fout(V ) = 0.1V . Check bydirect substitution that the functionV (t) = 10(t + 5e−0.1t)satisfies the ODE and the initial condition.Now assume that the hole is slowly growing in size, so that the flow rate out increaseswith time:fout(V, t) = 0.1(1 + 0.1t)V.Solve the ordinary differential equation for V (t) with this flow rate out, using either separation…
