Which of the following valves will incur maximum pressure drop for the same discharge of water

A 2" gate valve fitted in a pipe is replaced by a similar globe valve. Pressure drop in gate valve was Δp. For the same discharge, the pressure drop across globe valve is

Pressure drop due to pipe fittings can be estimated by the equation, , where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of t

Charge on a stationary oil drop in Millikan s experiment is ne. Potential difference between the plates is 400 volts. If mass of the drop is doubled without changing the charge, then potential drop re

Applying a pressure drop across a capillary results in a volumetric flow rate 'Q' under laminar flow conditions. The flow rate for the same pressure drop, in a capillary of the same length but half th

The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is Δp. If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows t

Foot valves provided in pumps are __________ valves

In water jet machining, the water jet is issued through a 0.3 mm diameter orifice at a pressure of 400 MPa. The density of water is 1000 kg/m3. The coefficient of discharge is 1.0. Neglecting all loss

In an experimental setup, the discharge through a triangular notch is 0.0074 m3 s-1 at an operating head of 0.1 m. The coefficient of discharge for the notch is 0.7. If the required discharge is 0.1 m

When a particular discharge is flowing in a horizontal pipe, a mercury-water U-tube manometer connccted to the entrance and throat of a venturimeter fitted in the pipe recorded a deflection of 25 cm.
