**1. Hydraulic system calculator**

This app will be very useful for people who work with hydraulic cylinders, pumps, motors, and pipes. By using this app we can design single-acting and double-acting cylinders. The area and volume of the cylinder can be calculated by entering the dimensions of the cylinder and parameters like pressure, oil flow. We can also calculate velocity, extraction, and retraction forces, time, and outflow by this app. By using this app we can calculate the flow rate, pressure, displacement, speed, torque, and power in the motor section. We can also calculate the displacement, flow rate, electric motor power, and total efficiency in the pump section. It can also calculate the pressure drop around an orifice and also it can calculate the piping parameters like velocity, cross-sectional area and Reynolds number can be calculated by using absolute or kinematic viscosity.

**2. Hydraulic calculator free**

This app can be used for the calculation of pressure drop in the design of liquid, gas, two-phase fluid pipelines, taking account of inline fittings will be carried out. The friction factor is calculated by using Poiseuille’s equation for laminar flow and Cole-brooks equation for transitional and turbulent flows. It can also be used for unit conversion of mass flow rate, volume flow rate, temperature, pressure, density.

**3. Hydraulic slide calculator**

This app can be used to do rapid hydraulic calculations to size hydraulic components during hydraulic system design. This app is not like other hydraulic calculator apps and the reason for that is it won’t require additional inputs to get answers, it would update itself as sliders are swiped and when the buttons are tapped. By using this app we can calculate the size of hydraulic cylinders, hydraulic pumps, and hydraulic motors.
