The plastic that pollutes water ways and ocean is a symptom of mismanagement that results throughout the biosphere in both terrestrial and aquatic environment.

Explanation:

We can reduce the microplastics by filtering tap water, avoiding usage of plastic containers, usage of beauty products with microbeads, limit eating of meat and fish.

The effective solution for for reducing this problem is giving up of plastics like avoid using bottles, plastic packaging, Don't use straws instead of that paper straws can be used.

The plastics are found everywhere in the environment and now it is found in sea water, fresh water, food and drinking water.

The products that contain plastics are tyres, synthetic clothing, tennis balls, laundry, tea bags and wet wipes.

Calculate the differential pressure in kPa across the hatch of a submarine 320m below the surface of the sea. Assume the atmosph

kicyunya [14]

Answer:

The pressure difference across hatch of the submarine is 3217.68 kpa.

Explanation:

Gauge pressure is the pressure above the atmospheric pressure. If we consider gauge pressure for finding pressure differential then no need to consider atmospheric pressure as they will cancel out. According to hydrostatic law, pressure varies in the z direction only.

Given:

Height of the hatch is 320 m

Surface gravity of the sea water is 1.025.

Density of water 1000 kg/m³.

Calculation:

Step1

Density of sea water is calculated as follows:

$S.G=\frac{\rho_{sw}}{\rho_{w}}$
